Question #1 What is the sum?​

Answer 1

Answer:

$\frac{7}{a + 8}+\frac{7}{a^2-64}$ = $\frac{14}{a^2+a-56}$

Step-by-step explanation:

Sum means finding the total of something. We can do this by using addition.

$\frac{7}{a + 8}+\frac{7}{a^2-64}$

In this problem, we will add the numerators and the denominators.

$\frac{(7+7)}{(a+8)+(a^2-64)}$

$\frac{14}{a^2+a-56}$

So, your answer is letter choice B.
