Question

Simplify 3ab + 4ab + 5

12ab
7ab + 5
not possible

Answer 1

7ab+5

Explanation:

add like terms (3ab+4ab=7ab)

5 doesn't have a like term so it stays by itself

Answer 2

Hey there! :)

3ab + 4ab + 5

In order to simplify this, we must add like terms. In addition, when simplifying, you can ONLY add like terms.

Since both "3ab" & "4ab" contain "ab," you are able to combine them together!

When combining like terms, you only add the numerical value, not the letters.

This leaves us with : 7ab + 5

Therefore, your answer is 7ab + 5
