Answer:

B.
(7x^2 + 11x)/(x^2 + 6x + 5)

Explanation:

The sum is worked as shown below:


(x)/(x + 1) + (6x)/(x + 5)

Use the common denominator to divide each denominator, then use the result to multiply the numerator, you'd have the following:


(x(x + 5) + 6x(x + 1))/((x + 1)(x + 5))

Use the distributive property of multiplication to solve


(x(x) + x(5) + 6x(x) + 6x(1))/((x(x + 5) + 1(x + 5))


(x^2 + 5x + 6x^2 + 6x)/(x^2 + 5x + x + 5)

Pair like terms


(x^2 + 6x^2 + 5x + 6x)/(x^2 + 6x + 5)


(7x^2 + 11x)/(x^2 + 6x + 5)

The answer is B.
