Answer:
8m and 12a
Explanation:
Like terms are terms that can be combined to condense a mathematical expression or equation.
Unlike Terms
Unlike terms are defined as terms that have different variables or powers.
- This means that for terms to be unlike they must either be multiplied by a different variable, like x and y, or have different exponents.
If terms meet either of these requirements, they are unlike. On the other hand, for terms to be like they must have both the same variable and power. The coefficients for the terms are not important.
Final Answer
All of the answer choices are to the first power, so the exponents are not important for this question. However, the last 3 answer choices all share the same variable. This means that they are all like terms.
The first answer choice, 8m and 12a, have different variables. This means that they cannot be combined and are unlike terms.
