Answer:
(3x - 25y)(3x + 25y)
Step-by-step explanation:
9x² - 625y² ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
Given
9x² - 625y²
= (3x)² - (25y)²
= (3x - 25y)(3x + 25y)
Answer:
160 yards
Step-by-step explanation:
P=2l+2w
P=2(3w-8)+2(w)
432=2(3w-8)+2(w)
432=6w-16+2w
432=8w-16
432+16=8w
448=8w
w=448/8
w=56yards
l=3(56)-8
l=168-8=160yards
