Question

Simplify:

2(4p – 3) + (p + 7)
A. 5p + 1
B. 5p + 4
C. 9p + 1
D. 9p + 13

Answer 1

C. 9p + 1

Explanation:

2(4p - 3) + (p + 7)

Step 1: Distribute 2 in the first term to both terms in the parenthesis. You can drop the parenthesis on the second term (p + 7)...

2(4p) + 2(-3) + p + 7

Now multiply

8p - 6 + p + 7

Now simplify by combining like terms

8p + p -6 + 7

9p + 1 (8p + p = 9p, -6 + 7 = 1)
