If you’re asking to simplify the problem, you would use distributive property. Basically, you multiply 8 by each component in the parentheses. 8(w)=8w and 8(3)=24. Therefore, the answer is 8w+24. If you don’t feel confident in your answer, you can always check. Let’s pretend w=5. Then we could say 8(5+3)=8(8)=64. To check, we would plug w into the simplified version of this expression, and if they’re the same, you’re answer is right. 8(5)+24=40+24=64
