That's not correct. The terms 2a and 3b are not like terms, so we cannot combine them to get 5ab. We simply leave it as 2a+3b.
If you had 2a+3a, then it would simplify to 5a
Similarly, 2b+3b = 5b
Or you could have 2ab+3ab = 5ab
The key is that the variable portions must match up to be able to add them.

Answer: k= -13/2 or k = 5
Step-by-step explanation:
8-5=3
3-5=-2
-2-5=-7
So the rule is -5 or subtract 5
For the volume you would use 1/2 b.h.h For a triangular prism. For an octagonal, you would use 1/2.a.p.h
b=Base
h=Height
(the other H) Hypotenuse
a=Apothom
p=Perimemter
