Answer:
[tex]\frac{7}{a + 8}+\frac{7}{a^2-64}[/tex] = [tex]\frac{14}{a^2+a-56}[/tex]
Step-by-step explanation:
Sum means finding the total of something. We can do this by using addition.
[tex]\frac{7}{a + 8}+\frac{7}{a^2-64}[/tex]
In this problem, we will add the numerators and the denominators.
[tex]\frac{(7+7)}{(a+8)+(a^2-64)}[/tex]
[tex]\frac{14}{a^2+a-56}[/tex]
So, your answer is letter choice B.
