Answer:
B) 5p^3 + 7p - 4
Step-by-step explanation:
This can be confusing because of the parenthesis, but to answer it all you have to do is group the like terms. Rearrange the problem so it looks like this:
3p^3 + 2p^3 + 5p + 2p - 8 + 4
Now that all the terms are neatly ordered we can simply add the coefficients of the terms with the same variable:
5p^3 + 7p - 4
