Step-by-step explanation:
the area of a trapezoid is
(a + b)/2 × x
a and b being the 2 bases. and x, as requested, is the height.
A
it does not matter which base is which, as long as we keep using them consistently.
so, let's assume a is the first base :
a = x + 5
and then for the second base
b = 2x - 1
now we use that in the main formula :
(x + 5 + 2x - 1)/2 × x = (3x + 4)/2 × x = (3x² + 4x)/2
A = (3/2)x² + (4/2)x = (3/2)x² + 2x ft²
B
now the height is increased by 4 ft.
that means we need to replace x by x + 4.
(3/2)(x+4)² + 2(x+4) = (3/2)(x² + 8x + 16) + 2x + 8 =
= (3/2)x² + (24/2)x + (48/2) + 2x + 8 =
= (3/2)x² + 12x + 24 + 2x + 8 =
= (3/2)x² + 14x + 32 ft²
with x being the original height, of course.

An octagon has a perimeter of 27 feet. If the sides of the octagon shrink by a scale factor of 8/9, what will the perimeter of the new octagon be
The perimeter of the new octagon be 24 feet.
What is the perimeter of octagon?A closed path that covers, encircles, or outlines a one-dimensional length or a two-dimensional shape is called a perimeter. A circle's or an ellipse's circumference is referred to as its perimeter.
There are numerous uses in real life for perimeter calculations. The measurement of the fence needed to completely enclose yard or garden is called the perimeter. How far a wheel or circle will roll in one revolution is determined by its circumference, or perimeter.
The length of each side of an octagon is the same. In order to calculate the perimeter of an octagon, multiply 8 by the length of its sides.
Given that the perimeter of an octagon is 27 feet
so the length of its side is 27/8 feet
if the side of the octagon shrink by a scale factor of 8/9
The side of new octagon is (27/8) * (8/9)
The side of new octagon is 3 feet.
So the perimeter of new octagon is 8 * side
⇒ the perimeter of new octagon = 8 * 3 feet

Which of the following best describes the difference in the results for the special products( A+B)^2 and ( A-B)^2
The difference between the expansions of (A + B)^2 and (A - B)^2 is the sign of the middle term. In the second case it is negative, due to the negative sign on B.
Which is the difference between the two expressions?Here we have two perfect square trinomials, these are:
(A + B)^2
(A - B)^2
Notice that the only difference between these is the sign of the second element.
Now we can expand these two expressions as:
(A + B)^2 = (A + B)*(A + B) = A^2 + 2AB + B^2
The second expression gives:
(A - B)^2 = (A - B)*(A - B) = A^2 + 2*A*(-B) + (-B)^2
= A^2 - 2AB + B^2
There we can see that the only difference between these two expansions is the sign of the middle term. Where in the second case it is negative, due to the negative sign on B.

Factorize the expression, 10ab (a − 2b)³ +24ab² (3a − 6b)²
Answer:
226a³b² - 824ab³ + 984b⁴
Step-by-step explanation:
We can factorize the given expression by expanding the two binomials and then combining like terms.
First, expand the two binomials:
10ab (a − 2b)³ +24ab² (3a − 6b)² = 10ab(a³ - 6a²b + 12ab² - 8b³) + 24ab²(9a² - 36ab + 36b²)
Then, combine like terms:
= 10ab(a³ - 6a²b + 12ab² - 8b³) + 24ab²(9a² - 36ab + 36b²)
= (10a³b - 60a²b² + 120ab³ - 80b⁴) + (216a³b² - 864ab³ + 864b⁴)
= (10a³b + 216a³b² - 60a²b² - 864ab³ + 120ab³ + 864b⁴ - 80b⁴)
= (10a³b + 216a³b² - 60a²b² - 864ab³ + 120ab³ + 864b⁴ - 80b⁴)
= (10a³b - 60a²b² + 120ab³ - 80b⁴) + (216a³b² - 864ab³ + 864b⁴)
= (10a³b + 216a³b² - 60a²b² - 864ab³ + 120ab³ + 864b⁴ - 80b⁴)
= (10a³b - 60a²b² + 120ab³ - 80b⁴) + (216a³b² - 864ab³ + 864b⁴)

You want the know the transformation that is applied to the red graph to make it be the black graph.
ObservationWe note that the vertex of the black graph is (-1, 4), which is 1 unit left and 4 units up from the vertex of the red graph.
The black graph opens downward, and has a slope of ±3 compared to the slope of ±1 for the red graph. This means it has been reflected across the x-axis and scaled by a factor of 3.
TransformationThe reflection and scaling can both be accomplished by multiplying the function by -3. The translation is accomplished by adding 4 to the function value to shift it up 4 units, and adding 1 to the x-value to shift the graph left 1 unit.

3x - y = 2
Step-by-step explanation:
pick 2 points on the line: (0, -2), (2, 4)
find slope (m):
m = (4-(-2))/(2-0) = 6/2 = 3
write the equation in point-slope form first:
y - y1 = m(x - x1)
plug in a point: (2,4)
y - 4 = 3(x - 2)
y - 4 = 3x-6
now write it in standard form: Ax + By = C
3x - 6 = y - 4

Of those surveyed, 264 respondents said that they preferred Candidate A. Determine a 95% confidence interval for the proportion of people who prefer Candidate A, rounding values to the nearest thousandth.
The 95% confidence interval for the proportion of people who prefer Candidate A is given as follows:
(0.438, 0.522).
What is a confidence interval of proportions?A confidence interval of proportions has the bounds given by the rule presented as follows:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which the variables used to calculated these bounds are listed as follows:
[tex]\pi[/tex] is the sample proportion, which is also the estimate of the parameter.z is the critical value.n is the sample size.The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.
The parameters for this problem are given as follows:
[tex]n = 550, \pi = \frac{264}{550} = 0.48[/tex]
Hence the lower bound of the interval is obtained as follows:
[tex]0.48 - 1.96\sqrt{\frac{0.48(0.52)}{550}} = 0.438[/tex]
The upper bound of the interval is obtained as follows:

Define Unitary Method.The unitary approach involves calculating the value of a single unit, from which we may calculate the values of the necessary number of units.
Define ratio and proportion.Two quantities are compared to form a ratio. An equality of two ratios is a percentage. How to format a ratio Analyze the ratio to see whether it is part to part or part to whole. Calculate the whole and the pieces as necessary.
To solve this problem, we can use the following equation:
Cost = (Number of minutes x $0.31) + $0.89 + $1.23
We know that cost is $6.15 and the call lasted 6 hours. Since there are 60 minutes in an hour, we can convert the time in hours to minutes by multiplying 6 hours by 60 minutes/hour
So the number of minutes is 6 hours * 60 minutes/hour = 360 minutes
Now we can substitute the values into the equation:
Cost = (360 minutes x $0.31) + $0.89 + $1.23
Cost = $111.6 + $0.89 + $1.23
Cost = $113.72
The equation does not match the $6.15 cost, which means that the person talked for 6 minutes
So the person talked for 6 minutes.

The sum of two numbers is 210 and their difference is 30. What are the two numbers?
Answer:
120 and 90
Step-by-step explanation:
let one number be x and the other y
x + y = 210 (sum = 210)
x - y = 30 (difference = 30)
add the two equations together
2x = 240
divide both sides by 2 to isolate x
x = 120
plug into 1st equation
120 + y = 210
subtract 120 from both sides
y = 90
We take the 2 numbers as 'x' and 'x-30' in order to find those numbers
We plug the values into the given equation
[tex]x + x - 30 = 210\\2x - 30 = 210\\\\2x = 240\\x = \frac{240}{2} \\x = 120\\x - 30 = 120 - 30 = 90\\[/tex]

What is system of equations?In algebra, a system of equations consists of two or more equations and looks for ways to solve them all together. A group of equations that have the same set of variables as solutions are referred to as a system of linear equations.
Let the constant cost be c and the per minute cost be denoted by m.
The equation for 5 minutes of the call is:
5.91 = 5m + c
c = 5.91 - 5m
The equation for 10 minutes of the call is:
10.06 = 10m + c
Substitute the value of c in the above equation:
10.06 = 10m + 5.91 - 5m
10.06 - 5.91 = 5m
4.69 = 5m
m = 0.93
Substitute the value of m:

system 1 :
3x + 2y = 7
4x + 7y = 17
system 2 :
12x + 2y = 28
4x + 7y = 17
the first equation in the second system is not a multiple of either equation in the first system, and the second equation in the second system is the same as the second equation in the first system.
thus, the systems are not equivalent.
"12x" gives us the idea what the factor would have to be (4 or 3), if the second equation of the second system would be a multiple of any of the equations in the first system.
as we would have to multiply 3x by 4 to get 12x, and 4x by 3 to get 12x.
but then 2y×4 = 8y, or 2y×3 = 6y, and that is not the same as 2y (part of the first equation of the second system).
that is why this first equation of the second system is not a multiple of either equation in the first system.
and that makes it impossible for both systems to be equivalent. that the second equations are identical, is then not relevant anymore.
