Question

Four expressions are shown below:

A. 2(4x + 2)
B. 2(3x + 3)
C. 6x + 6
D. 8x + 4

Which two expressions are equivalent to 2(3x + 2 + x)?

A and D
B and D
A and C
C and B

Answer 1

I think A and D but idk

Answer 2

is it? A and D?

Answer 3

Yes that's correct

3x+2+x = 3x+x+2 = 4x+2

So this shows that 2(3x + 2 + x) is the same as 2(4x + 2)

This confirms choice A

When you distribute the 2 through with 2(4x + 2), you get,
2(4x + 2) = 2*4x + 2*2 = 8x + 4
which confirms choice D
