Answer: 22b

Explanation:

Our task is to simplify the expression
\sf{4b+18b}.

We will do it by combining the like terms:

4b + 18b = 22b

Just add 4 + 18, and copy the 'b'.

--- What are like terms? ---

Like terms are terms that share the same exponent, variable, etc. Examples of like terms would be 7x + 4x; 6y + 2w are NOT like terms, because their variables are different.

2x + 7x² aren't like terms either, because they have different exponents.
