Answer:
(x - 9)(x + 8)
Step-by-step explanation:
Given
x² - x - 72
Consider the factors of the constant term (- 72) which sum to give the coefficient of the x- term (- 1)
the factors are - 9 and + 8, since
- 9 × 8 = - 72 and - 9 + 8 = - 1, thus
x² - x - 72 = (x - 9)(x + 8)
600 because you do five times twelve which is 60 then u add the zero
Total perimeter is 522 ft. I will guess the gym is a big rectangle.
Therefore, Perimeter of a rectangle = 2L + 2W
P= 2L+ 2W
We know 80 ft wide. so now we plug and chug the equation we came up with
P=522 ft
P=2L+ 2(80)
522=2L+ 160
L= 181
hope that helps

Answer:
205 years
Step-by-step explanation:
E=68 years
C=E+17=68+17=85 years
D=E-16=68-16=52 years
Total=E+C+D=68+85+52=205 years
