please solve and explain, thanks!! :))

Answer:
B
Step-by-step explanation:
Its B because you distribute each term inside the parenthesis by the number out side
4×2x= 8x
4×3= 12
Get rid of the parenthesis after distributing
which makes 8x+12
Answer:
B. 8x + 12
Step-by-step explanation:
First you'd start with the parentheses because of PEDMAS. But because you can't do anything in there, you go to multiplying 4 by each item inside the parentheses. 4x2x gives 8x. 4x3 gives 12. Leaving you with 8x+12. Hope that helps! :)
