4 0

Answer:

Step 3 is incorrect

Step-by-step explanation:

4(-1/2x + 7) + 5x = 15

-2x + 28 + 5x = 15

3x + 28 = 15

3x + 28 - 28 = 15 - 28

3x = -13

s = \sqrt{25} = 5 ← length of side

perimeter = 4s = 4 × 5 = 20 m

Mariana [72]

Answer:

x = 7.2

10x = 72

divide by 10 to get x alone:

x = 7.2
