Answer 1

(A) 7/(m+4)

Explanation:

When fractions have a common denominator, you add them by adding their numerators and using that sum with the common denominator.

Here, you may be able to cancel a common factor from numerator and denominator to simplify the expression further.

`(4m-17)/(m^2-16)+(3m-11)/(m^2-16)=(4m-17+3m-11)/(m^2-16)=(7m-28)/(m^2-16)\\\\=(7(m-4))/((m+4)(m-4))=\boxed{(7)/(m+4)}`
