Question

1. consider the expression: $5u + 2v - 5u$

8a select the pair of like terms:
-5u a 5u b
2v c

Explanation:

Like terms are terms with the same variable (or no variable) raised to the same power. In the expression \(5u + 2v - 5u\), \(5u\) (option B) and \(-5u\) (option A) have the same variable \(u\) with the same exponent (1), so they are like terms. \(2v\) has a different variable (\(v\)) so it's not like the others.

Answer:

A. \(-5u\), B. \(5u\)
