If x > 7, which of the following is equal to (x^2 - 8x + 16)/(x^2 - 16) ?
Choose the correct answer:
A) (x + 4)/(4(x - 4))
B) (x - 4)/(x + 4)
C) (x - 2)/(x + 4)
D) (x + 4)/(x - 4)
E) (x - 8)/(x - 4)
(x^2 - 8x + 16)/(x^2 - 16)   = (x - 4)(x - 4) / (x + 4)(x - 4)   =(x - 4)/(x + 4)   B. (x - 4)/(x + 4)
