Answer:
Yes, 9 and 6 are like terms.
Explanation:
Like terms are the terms that have the same variable — that also includes same degree too.
Some examples are:
- x and 2x are like terms because both have x-term and they have the same degree.
- 2y and 3y are like terms because both have y-term and they have the same degree.
- 3y and 2y² are not like terms because both have y-term but they have different degree.
In this case, both are like terms because 9 and 6 both are constant — they can be added to form new number which is 15. While terms that are not alike will be stuck as how they are. (e.g x²+x is just x²+x, it cannot be added together.)
