What is the solution to |2x + 3| = 15? A. x = 6 B. x = 6 or x = -6 C. x = 6 or x = -9 D. No solutions exist.

C. X=6 or X= -9

First Explanation:

2x + 3 - 3 = 15 - 3 (subtract 3 from 3 and 15)

You should get 2x = 12

Then divide 2x by 2

Divide 12 by 2 which you should get
X = 6

Second Explanation:

2x + 3 - 3 = 15 - 3 (subtract 3 from 3 and 15)

You should get 2x = -18

Then divide 2x by 2

Divide -18 by 2 and you should get
X = -9

Recall that area of the triangle is 1/2*(base)*(height)1/2*(13)*(17) = 110.5the answer is 110.5
