Question

What is the simplified expression for 5 a b + 9 a b minus a b?

Answer 1

Answer:

13ab

Step-by-step explanation:

When you add the 5 and 9 it will give you 14 but you still have to subtract the 1ab(there is a 1 in front of variables that don't have a visible number.) So it will be 13 a b.
