Which of the following expressions cannot be simplified?
A) 8x-5x
B) 8x-1
C -(8x+3)
D 8(x-2)
Answer:
B) 8x-1
Step-by-step explanation:
A) 8x-5x Like terms = 3x
B) 8x-1 Not like terms 8x-1
C -(8x+3) Distribute the minus sign -8x -3
D 8(x-2) Distribute the 8 8x - 16
Answer:
B. 8x - 1
Step-by-step explanation:
Notice that all of these expressions can be simplified except for option B. 8x-1.
Option A has two like terms, 8x and -5x which could be reduced to 3x
Option B has two distinct terms, 8x and -1 which can only be combined into 8x-1
Option C has a leading negative, and can be simplified with the distributive property to be -8x + -3
Option D has a leading 8 that can be distributed to the term (x-2) to form 8x - 16.
Thus, choose option B.

A triangle has a base of (3x + 7) and a height of (5x - 1). A second
triangle is drawn with a base that is tripled and a height that is
doubled. Find the difference between the area of the original triangle
and the area of the new triangle.
Answer:
The difference between the area of the original triangle and the area of the new triangle is [tex]\Delta A_{\bigtriangleup} = \frac{5}{2}\cdot (3\cdot x +7)\cdot (5\cdot x -1)[/tex].
Step-by-step explanation:
The equation for the area of a triangle ([tex]A_{\bigtriangleup}[/tex]) is:
[tex]A_{\bigtriangleup} = \frac{1}{2}\cdot b \cdot h[/tex]
Where:
[tex]b[/tex] - Base, dimensionless.
[tex]h[/tex] - Height, dimensionless.
The expression for each triangle are described below:
First Triangle ([tex]b = 3\cdot x + 7[/tex], [tex]h = 5\cdot x - 1[/tex])
[tex]A_{\bigtriangleup,1} = \frac{1}{2}\cdot (3\cdot x+7)\cdot (5\cdot x -1)[/tex]
Second Triangle ([tex]b = 3\cdot (3\cdot x+7)[/tex], [tex]h = 2\cdot (5\cdot x -1)[/tex])
[tex]A_{\bigtriangleup,2} = 3\cdot (3\cdot x+7)\cdot (5\cdot x -1)[/tex]
The difference between the area of the original triangle and the area of the new triangle is:
[tex]\Delta A_{\bigtriangleup} = A_{\bigtriangleup,2}-A_{\bigtriangleup,1}[/tex]
[tex]\Delta A_{\bigtriangleup} = 3\cdot (3\cdot x+7)\cdot (5\cdot x-1)-\frac{1}{2} \cdot (3\cdot x+7)\cdot (5\cdot x-1)[/tex]
[tex]\Delta A_{\bigtriangleup} = \frac{5}{2}\cdot (3\cdot x +7)\cdot (5\cdot x -1)[/tex]
The difference between the area of the original triangle and the area of the new triangle is [tex]\Delta A_{\bigtriangleup} = \frac{5}{2}\cdot (3\cdot x +7)\cdot (5\cdot x -1)[/tex].
4(-8x+5) - (-33x-26)
Answer:
Step-by-step explanation:
Use distributive property a(b+c) = a*b +a*c
4(-8x + 5) - (-33x - 26) = 4*-8x + 4 *5 - 33x * (-1) - 26*(-1)
= -32x + 20 + 33x + 26
{add like terms}
= -32x + 33x + 20 +26
= 1x + 46
a circle has a radius of 7ft. Find the radian measure of the central angle 0 that intyercepts an arc of length 16ft
Answer:
2.29 rads
Step-by-step explanation:
The length of the arc of a circle of radius r is given by;
l = rθ ---------------------------(i)
Where;
l = length of the arc
θ = central angle o that intercepts that arc and measured in radians.
From the question:
l = 16ft
r = 7ft
Substitute these values into equation (i) as follows;
16 = 7θ
Make θ subject of the formula
θ = [tex]\frac{16}{7}[/tex]
θ = 2.29
Therefore, the radian measure of the central angle is 2.29 rads
True or False
15. (True or False) Any 3 distinct points are always coplanar.
16. (True or False) Any 2 distinct circles are always coplanar.
17. (True or False) If 2 lines intersect once then the lines are coplanar.
18. (True or False) Two lines that are skew can sometimes intersect.
19. (True or False) An angle and a circle can have more than 3 intersections
20. (True or False) Two distinct circles can have more than 2 intersections.
21. (True or False) Any given line and point are always coplanar.
Answer:
15. True
16. False
17. True
18. False
19. True
20. False
21. True
Step-by-step explanation:
15. The three points can be taken as being two points on a line adjacent to a point which always forms a plain when the ends of the line are connected to the point
16. The two circles can be on different planes
17. With one line fixed, the other line can be rotated until both lines are in the flat plane
18. The definition of skew lines are lines in different planes that are not parallel and that do not intersect
19. Whereby the angle crosses the circumference of the circle twice, the number of intersections = 4
20. Two distinct circles can only intersect twice
21. A plane can always be drawn with any three points

Find the value of a. Then find the angle measures of the polygon.
a =

(2aº caº
a
Sum of angle
measures: 360°
Answer:
In the given quadrilateral, two angles measure 60° and other two angles measure 120°.
Step-by-step explanation:
As we know sum of all interior angles of a polygon with 'n' sides is,
Sum of interior angles = (n - 2) × 180°
= (4 - 2) × 180° [for a polygon with n = 4]
= 360°
a + a + 2a + 2a = 360°
6a = 360°
x = 60°
Measure of angles = a° = 60°
And angles having measure = 2a° = 2(60)°
= 120°
Therefore, in the given quadrilateral, two angles measure 60° and other two angles measure 120°.

a mouse runs across a 5.56 m kitchen floor in 3.42 seconds.What is the velocity of the mouse?
Answer:
v = 1.62 m/s
Step-by-step explanation:
Given that,
Distance covered by the mouse is 5.56 m is in 3.42 seconds.
We need to find the velocity of the mouse. It is equal to the total distance covered divided by time taken. So,
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{5.56\ m}{3.42\ s}\\\\v=1.62\ m/s[/tex]
So, the velocity is 1.62 m/s.

5b - 6 = 27
5b = 33
b = 33/5

x-intercept: 3
y-intercept: 2
Answer:
y = -2/3x + 2
Step-by-step explanation:
Hey there!
Well since we already got the y-intercept to find slope we'll use the points,
(3,0) and (0,2).
Formula: [tex]\frac{y^2 - y^1}{x^2 - x^1}[/tex]
Plug in the given points,
[tex]\frac{2 - 0}{0 - 3}[/tex]
Slope = -2/3
Slope-intercept: y = -2/3x + 2
Hope this helps :)
Answer:
y = -2/3x + 2 or
2x + 3y = 6 (standard form).
Step-by-step explanation:
I am assuming you want the equation of the straight line that passes through these 2 points.
The 2 points are (3, 0 ) and (0, 2).
The slope of the line = (2 - 0) / (0 - 3)
= -2/3.
The equation is y = -2/3x + 2 ( as 2 is the y-intercept).
In standard form this is :
3y = -2x + 6
2x + 3y = 6.
What’s the value of X in this triangle
Answer:
x = 85
Step-by-step explanation:
Step 1: Solve x
∠x = 180 - 27 - 68
∠x = 85
Therefore angle x equals 85
Answer:
85 degrees
Step-by-step explanation:
The sum of the angles of a triangle always add up to 180 degrees.
Here, we have two angles already given, so we can write:
27 + 68 + x = 180
95 + x = 180
Subtract 95 from both sides:
x = 180 - 95 = 85
The answer is thus 85 degrees.

Thus the 2 ratios are equivalent and simplify to 5 : 2
Find the missing number to make these fractions equal.
Answer:
66/8 = 3/4Step-by-step explanation:
Let the unknown number be x

Answer:
6
Step-by-step explanation:
Given
[tex]\frac{3}{4}[/tex] = [tex]\frac{?}{8}[/tex]
The 4 on the denominator is multiplied by 2 to obtain 8
The same operation must be applied to the numerator to make them equal.
Thus
3 × 2 = 6
[tex]\frac{3}{4}[/tex] = [tex]\frac{6}{8}[/tex] ← are equal fractions
The product of six and a number increased by six?
Answer: 6•(n+6)
Step-by-step explanation:
n is number
can be any letter
Answer:
6(n+6)
Step-by-step explanation:
the product means multiplication so you're going to need to multiply 6 by the number increased by 6. n represents the number, so n increased by 6 would be n+6. the parentheses represent the multiplication. put it together and you get the answer 6(n+6)
Move the center of rotation back to the origin (0, 0) of the coordinate plane. Now alter pentagon ABCDE by moving one or more line segments on the pentagon to a different location. Rotate the pentagon using the slider. How many times does the pentagon map back onto itself in this situation? What can you conclude about the kinds of polygons that can map back onto themselves? Describe them.
The changed pentagon maps back onto itself only one time, when the value of α is 360°. A polygon must be regular to map back onto itself more than once. In a regular polygon, all of the sides are equal and all of the angles are equal.
