Answer:
A. [tex]3(x+2) = 3x+6[/tex]
Step-by-step explanation:
Lets look at each of these
A
[tex]3(x+2) = 3x+6\\\\3x+6=3x+6[/tex]
B
[tex]3x+2x=x^2(3+2)\\\\3x+2x=5x^2[/tex]
C
[tex]3x+2=3(x+2)\\\\3x+2=3x+6[/tex]
D
[tex]-3(2+x)=-6x-3\\\\-6-3x=-6x-3[/tex]
As we can see, A was the only option that simplified to equal itself, so that is our answer.
