9.
9v + 9 + v + v
= 11v + 9
To solve the expression 9v + 9 + v + v, we can simplify it by combining like terms together.
Combining the terms with "v", we have:
9v + v + v
This can be simplified as:
9v + 2v
Adding the coefficients together, we get:
11v
Therefore, the final simplified expression is 11v.
