Step-by-step explanation:
A perfect square has all side lengths the same so...
9*9=81
81
Explanation:
A perfect square has lengths that are all the same, so if one side is 9 the other sides must be 9. Then using the formula to find area (A=LxW) we can multiply 9 x 9 to get a area of 81.
A=9x9
A=81

The area of the football field is 57,600 square feet. If the width of the field is 4/9 the length,what is the length of the football field ?
Answers
Answer:
360 feet.
Step-by-step explanation:
Let x = length, then the width is 4x/9 feet.
So we have the equation:
x * 4x/9 = 57600
4x^2 / 9 = 57600
4x^2 = 57600 * 9
x^2 = 57600 * 9 / 4
x = √57600 * 3 / 2
x = 240* 3/2
x = 360 feet.

Answer:
4. x = 50
5. x = 5
Step-by-step explanation:
For question 4:
Multiply both sides: x + 35 = -15Move the constant to the right: x = -15 - 35Calculate: x = -50For question 5:
Move the constant to the right: -3x = -17 + 2Calculate the sum: -3x = -15Divide both sides: x = 5Answer:
4) x= -50
5) x= 5
Step-by-step explanation:
Number 5
Simplifying
-3x + -2 = -17
Reorder the terms:
-2 + -3x = -17
Solving
-2 + -3x = -17
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2' to each side of the equation.
-2 + 2 + -3x = -17 + 2
Combine like terms: -2 + 2 = 0
0 + -3x = -17 + 2
-3x = -17 + 2
Combine like terms: -17 + 2 = -15
-3x = -15
Divide each side by '-3'.
x = 5
Simplifying
x = 5

we’re using x as the variable representing hours worked (other than the 4 hours already)
knowing this, we can set it up so that we have

x > 5

What is the area of a square in terms of x & y, if one side is 2x-y?
Answers
Answer: (2x-y)^2
Step-by-step explanation:
The area of a square is given by the formula A = s^2.
We know that the length of one side is s = 2x-y. We can substitute this into our area equation:
A = (2x-y)^2
If you need to multiply out the answer:
A = (2x-y)(2x-y)
A = 4x^2-4xy+y^2

O Jason's camp counselor job pays a higher hourly rate than Mia's lifeguard job.
Jason's camp counselor job pays a lower hourly rate than Mia's lifeguard job.
Answers
Answer:
The correct statement is (3).
Step-by-step explanation:
Jason's hourly pay rate as a camp counselor for the summer is:
J = $9 / hour.
The table representing Mia's pay as a lifeguard for the summer is as follows:
Days Hours worked Amount paid
Tuesday 6 $52.50
Thursday 8 $70,00
Saturday 5 $43.75
Compute Mia's hourly rate for Tuesday: [tex]\frac{\$52.50}{6}=\$8.75[/tex]
Compute Mia's hourly rate for Thursday : [tex]\frac{\$70.00}{8}=\$8.75[/tex]
Compute Mia's hourly rate for Saturday: [tex]\frac{\$43.75}{5}=\$8.75[/tex]
Thus, Mia's hourly rate as a lifeguard for the summer is,
M = $8.75 / hour
This implies that Jason's camp counselor job pays a higher hourly rate than Mia's lifeguard job.
Thus, the correct statement is (3).
