Answer 2

Answer:

The equivalent expression is C) -28x + 21

Step-by-step explanation:

Let's consider the following expression.

In order to find the equivalent expression, we can use the distributive property of multiplication over subtraction.

-7 × 4x - (-7) × 3

- 28x - (-21)

- 28x + 21

The equivalent expression is

C) -28x + 21
