Use the distributive property to evaluate 4 (2x-1) when x=3.

Select one:

a. 4

b. 16

c. 20

d. 23

For this case we have the following expression:

4 (2x-1)

For x = 3 we have:

4 (2 (3) - 1)

Rewriting:

4 (6-1)

Using distributive property we have:

4 * 6 - 4 * 1

Rewriting

24 - 4 = 20

Answer:

Therefore, the correct answer is:

c. 20
