$(5v^{3} + 5v^{2} + 9v + 9) + (8v^{3} + v + 2)$

Explanation:

Step1: Group like terms

$(5v^3 + 8v^3) + 5v^2 + (9v + v) + (9 + 2)$

Step2: Combine $v^3$ terms

$13v^3 + 5v^2 + (9v + v) + (9 + 2)$

Step3: Combine $v$ terms

$13v^3 + 5v^2 + 10v + (9 + 2)$

Step4: Combine constant terms

$13v^3 + 5v^2 + 10v + 11$

Answer:

$13v^3 + 5v^2 + 10v + 11$
