Answer:
The original price of the shoes was $90.
Step-by-step explanation:
25% off means the price Joe paid for it is 75% of the original price.
Set up an equation:
75/100 = 67.50/x
Cross multiply
75 × x = 100 × 67.50
75x = 6750
x = 90
Check our work:
First solve for 25% off of 90 (our answer).
25% = 0.25
90 × 0.25 = 22.50
Next, subtract the discount from 90.
90 - 22.50 = 67.50
67.50 was what Joe paid so this is correct.
(x + 2)(- 8x + 1) are your factors.
if 15 cars were washed there would be $52.50
Answer:

Step-by-step explanation:
The area of the square whose diagonal 712 units is 253472 units²
Step-by-step explanation:
You can find area of a square by using one of the two rules:
1. Area of a square = s², where s is the length of its side
2. Area of a square = , where d is the length
of its diagonal
∵ The length of the diagonal of the square is 712 units
∵ The area of the square =
∴ The area of the square =
∴ The area of the square = 253472 units²
The area of the square whose diagonal 712 units is 253472 units²
