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
 
 Therefore, the correct answer is:
 c. 20
