Answer:
6v^2 - 35v + 6wv - 42w - 49
Explanation:
Use distributive property
First multiply 6v to each term within the second set of parentheses
6v^2 - 42v
Now multiply 6w to each term within the second set of parentheses
6wv - 42w
Next multiply 7 to each term within the second set of parentheses
7v - 49
Add all of these numbers together
6v^2 - 42v + 6wv - 42w + 7v - 49
Combine like terms
6v^2 - 35v + 6wv - 42w - 49
No more like terms so the expression is simplified
