Answer:
-10wx - 20x
Explanation:
Well the first step is to just take what's on the outside of the parenthesis times what's on the inside. So you're essentially breaking this problem down into 5x(-2w) + 5x(-4). So start with the first set. 5x(-2w) = -10wx. Now the second set. 5x(-4) = -20x. Now your equation looks like -10wx - 20x. All that's left is to combine like terms, however you don't have any like terms in what you have left. So your answer is just -10wx - 20x. Hope this helped!
