Answer:
the answer is 4(3a+2)
Step-by-step explanation:
first you do 3a + 2 you do that first because its in parentheses you always have to do that first. Anyways 3a+2= 5a and you have to multiply 4 by 5a because its outside the and that would give you
4(3a+2)=20a and you started with 12a + 8 so add that to check your answer
