Answer:
21 for the first one, 144 for the second
Explanation:
If you're seeing the same problem I am in class, the rule is: N + 9
N is equal to 12 in this equation
12 + 9 is 21.
So, the answer is 21
If there is a second problem, like there is for the one I'm seeing, then this is the answer for that-
Is 12(12)= 144
Hope this helps!
(By the way, I'm horrible at math so this could be completely wrong)
