C) 16π ft
Step-by-step explanation:
Fencing is perimeter. The perimeter of a circle is the circumference.
The circumference of a circle is pi time diameter
C= pi*d
We know the diameter is 16
C = 16*pi ft
We will need 16 pi ft of fencing
Factor the following:
x^2 - 16 x + 63
The factors of 63 that sum to -16 are -7 and -9. So, x^2 - 16 x + 63 = (x - 7) (x - 9):
Answer: (x - 7) (x - 9)
