Which expression is equivalent? −7(4x − 3) a) 28x + 21 b) 28x − 21 c) −28x + 21 d) −28x − 21

The equivalent expression is C) -28x + 21

Step-by-step explanation:

Let's consider the following expression.

-7 × (4x - 3)

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

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
