Answer: it right
Step-by-step explanation:
Answer: D. 12h + 21h2
Step-by-step explanation: The answer is D,
because when you devide 12h/3h = 4
and for the other value 21h2/3h=7h
4 + 7h
if you perform the same operation with the rest of answers you will get a minor values if you compare with this results, because of that the answer with the greatest common factor is D.
Step-by-step explanation:
you're going to solve for y in the first equation and then substitute it in for the second equation and solve.
