Answer:
The answer is "Option A".
Step-by-step explanation:
- Like terms are also known as the same variables that are correlated with the same value. This primarily differs from empirical experiences. It includes other definitions, which are condensed and simplified to make algebraic concepts simpler.
- In the given expression "[tex]\ 4m\ -\ 9\ + \ 3n\ +\ 2[/tex]" there are four terms, in which -9 and 2 are like terms, because both are integers, and others are unlike terms, that's why other choices were incorrect.
