If x > 7, which of the following is equal to (x^2 + 8x + 16)/(x^2 - 16 [#permalink]
(x^2 + 8x + 16)/(x^2 - 16)
= (x + 4)(x + 4) / (x + 4)(x - 4)
=(x + 4)/(x - 4)

If x > 7, which of the following is equal to (x^2 + 8x + 16)/(x^2 - 16) ?

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)


Let’s simplify the given equation:

(x^2 + 8x + 16)/(x^2 - 16)

(x + 4)(x + 4)/[(x - 4)(x + 4)]

(x + 4)/(x - 4)
