The perimeter of a rectangular pool is 48 feet. Its length is 4 feet
more than its width.
Let the width of the pool be represented by x.
Which equation below can be used to describe the situation?
A x(x + 4) = 48
B 2x + 2(x + 4) = 48
С2x + 2x + 4 = 48
D 2x(x + 4) = 48
Answer:
B
Step-by-step explanation:
let's represent the width with x, if we represent the width with x then that makes the length x+4. Therefore the perimeter would be 2x+2(x+4)=48

Which statement describes the graph of this polynomial function?
f(x)= x4+ x3 - 2x2
The graph crosses the x-axis at x = 2 and x = -1 and touches the x-axis at x = 0.
The graph touches the x-axis at x = 2 and x = -1 and crosses the x-axis at x = 0.
O The graph crosses the x-axis at x = -2 and x = 1 and touches the x-axis at x = 0.
The graph touches the x-axis at x = -2 and x = 1 and crosses the x-axis at x = 0.
Answer:
Option (3)
Step-by-step explanation:
Given function is,
f(x) = x⁴ + x³ - 2x²
= x²(x² + x - 2)
= x²(x² + 2x - x - 2)
= x²[x(x + 2) - 1(x + 2)]
= x²(x + 2)(x - 1)
So the factored form of the polynomial function is,
f(x) = x²(x + 2)(x - 1)
For x - intercepts,
F(x) = x²(x + 2)(x - 1) = 0
x = -2, 1
This function has even multiplicity = 2 at x = 0.
Therefore, graph of the function will touch the x-axis at x = 0
And at other roots x = -2, 1 has odd multiplicity = 1, so the graph will cross the x-axis.
Option (3) will be the correct option.

What is the constant of proportionality between y and x in the graph?
Answer:
y=3x
Step-by-step explanation:
y=kx, where k is constant
3y, 1x...so 3y = 1x
check: looking at the graph at 4.5y, 1.5x where y and x intersect...
4.5=3(1.5)

Find the distance between the points A(10,-9) and B(8,7) round your answer to the nearest hundredth
Answer:
16.12 units
Step-by-step explanation:
These two points create a right triangle whose diagonal (hypotenuse) represents the desired distance.
Going from B(8, 7) to A(10, -9) involves two steps: Moving 2 units to the right from B(8, 7) to A(10, -9), and moving 16 steps down from B(8, 7) to A(10, -9).
Thus, the horizontal side of the triangle in question has length 2 units and the vertical side 16 units.
The length of the diagonal (which is the desired distance) is then
|AB| = +√(2^2 + 16^2) = +√(4 + 256) = +√260
To the nearest hundredth, this is |AB| = 16.12 units

8. Alex is buying a pair of new Nikes. Champs decided to apply a markdown of 35%. He found a coupon online for an additional 10% discount. What is the final cost after the markdown and then coupon is applied if the Nikes original cost is $130?
Answer:
175
Step-by-step explanation:
Your friend really wants to buy the newest coolest cell phone which will cost him $310 he gets a job detailing cars and suvs and plans to save all the money he earns if he gets paid $60 to detail a car and $85 to detail an suv which of the following inequalities can be used to determine how many of each he must detail in order to earn at least $310
Answer:
[tex]60c + 85s \geqslant 310[/tex]
Step-by-step explanation:
He needs to earn at least $310 so $60 per car is 60c and $85 per SUV is 85s. So the answer is the third option.
The required inequality:
60x + 85y >= 310
What is inequality?In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.
Given, a person gets paid $60 to detail a car and $85 to detail an SUV.
Let's assume he needs to detail x number of cars and y number of SUVs to earn at least $310.
Then, the amount earned by detailing x cars and y SUVs can be expressed as:
60x + 85y
According to the problem statement, he wants to earn at least $310, so we can write the inequality:
60x + 85y >= 310
This is the required inequality to determine the number of cars and SUVs he needs to detail in order to earn at least $310.

What is the number?
The number is
Answer:
7.2 + x = 10
Step-by-step explanation:
I did 7.2 + x = 10 Because there was suspose to be a number in between
that we do not know so you have to put 7.2 + x = 10
Then... For the next question (The same question but asking the number in between) The second Question you do 7.2 - 10 and you get 2.8
The equation to describe the situation when the sum of 7.2 and a number is 10 is given so it is 7.2 + x = 10.
Calculation of an equation:Since
The sum of 7.2 and a number is 10.
So here we assume the number be x
So,
7.2 + x = 10
x = 2.8
hence, The equation to describe the situation when the sum of 7.2 and a number is 10 is given so it is 7.2 + x = 10.

Solve with Quadratics
Answer:
x = 1 ± [tex]\sqrt{6}[/tex]
Step-by-step explanation:
Given
2x² - 4x = 10 ( divide through by 2 )
x² - 2x = 5
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 1)x + 1 = 5 + 1
(x - 1)² = 6 ( take the square root of both sides )
x - 1 = ± [tex]\sqrt{6}[/tex] ( add 1 to both sides )
x = 1 ± [tex]\sqrt{6}[/tex] ← exact solutions
