Question

What is the sum of the rational expressions below?

Answer 1

D

Explanation:

Given

`(2x+7)/(x+5)` +
`(x-3)/(x+5)`

Both fractions have a common denominator of x + 5

Thus we can add the numerators leaving the common denominator

=
`(2x+7+x-3)/(x+5)` ← simplify numerator

=
`(3x+4)/(x+5)` → D
