Question

Which is equivalent to 4(x + 7)?

Question 4 options:

4x + 7


4x + 28


4 + 7x


11x

Answer 1

Simple....

you have:  4(x+7)

To simplify it..distribute..

4(x+7)

4*x=4x
and
4*7=28

Leaving you with...

4x+28

As we can see B is 4x+28

Thus, your answer.

Answer 2

4x+28 is the right answer because you would use the distributive property which makes  4(x+7)------> 4x+28
