Which pair shows equivalent expressions?

3 (x+2) = 3x+6

3x + 2x = x2 (3+2)

3x+2 - 3 (x+2)

-3 (2+) - -6-3

the answer is 3 (x+2) = 3x=6

Step-by-step explanation:

3 (x+2) = 3x+6 = 3 multiplies by x=3x 3 multiplied by 2=6 so it would be 3x+6

3x + 2x = x2 (3+2) = 3x+2x = 5x its impossible to do 2x multiplies by 3 cause there is no similar variables there needs to be x in both

3x+2 - 3 (x+2) = same as above there's no similar variables

-3 (2+) - -6-3 = this just doesnt work at all
