Answer:
8x + 4
Step-by-step explanation:
To answer, we have to make sure to hand out the 4 evenly so that each number or variable within the parentheses gets multiplied by 4:
4(2x + 1) = 8x + 4
As you can see, we multiplied each number inside by the number outside, and we got 8x + 4 as our answer.
Hope this helps :)
