Answer with Explanation please! Thank you!

Anna [14]

Answer:

The answer is D.

Step-by-step explanation:

First you have to get rid of brackets by expanding :

$3 {q}^{2} + {r}^{3} + 5r - 8q + 2( {q}^{2} + r)$

$= 3 {q}^{2} + {r}^{3} + 5r - 8q + 2 {q}^{2} + 2r$

Next you have to simplify by collecting like terms :

${r}^{3} + 3 {q}^{2} + 2 {q}^{2} + 5r + 2r - 8q$

$= {r}^{3} + 5 {q}^{2} - 8q + 7r$
