Answer 1

4, 6, 7, 1, 5

Explanation:

(4) Fractions need common denominators to add them. So, we start by factoring in order to manipulate them more.

(6) Looking at the first fraction, cancel out the (x+2) because you can divide it out from both the numerator and denominator.

(7) Multiply the first fraction by (x+4)/(x+4) to get the same denominator as the second fraction.

(1) Now add the two fractions.

(5) Simplify the numerator, and expand the denominator.

woohoo!
