Question

The expression 8 + 2x can be written as _____.

4(2 + x)
2(4 + x)
2(4 + 2x)

Answer 1

4 plus x then 5 plus two subtracted by 70 million x 50

Answer 2

Answer: 2(4 + x)

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.
