150 - x- 2 – 2x = 120 + 2x

First collect like terms on one side

150-2-120=2x+x+2x

148-120=3x+2x

28=5x

Let me change the positions so it could be easier to solve

5x=28

x=28/5

x=5.6

Step-by-step explanation:

I hope I explained well, please give me brainliest

38 square feet

Step-by-step explanation:

Triangle 1: area = bh / 2 -> 3x4 / 2 = 6 square feet

Triangle 2: area = 4x4 / 2 = 8 square feet

Rectangle: area = 8x3 = 24 square feet

6 + 8 + 24 = 38 square feet
