Add like terms
one way to understand adding like terms is the distributive propery
a (b+c) = ab+ac so
8c+5c = (8+5) c
then add 8+5=13
(13) c
13c so
13c+21
we can't add them together since the 21 doesn't have a placeholder with it
the answer is 13c+21

13c + 21 I'm pretty sure it stays like that because of the variable C.
