Answer: 2(4 + x)
Step-by-step explanation:
i just multiplied across the parentheses. we can rule out the first option, because it would multiply out to be 8 + 4x.
the second option is the one that i calculated second, so i knew that i could rule out the last one my default.
just for kicks, if we multiplied the third option, it would come out to 8 + 4x.
