7.  Austin solved the equation as shown below.  Which correctly describes the error that Austin made in his work?

• Austin did not combine 7x and 8x correctly

• 1. Austin did not combine -3 and -9 correctly

• 1. Austin did not divided correctly

9.  Which of the following shows the equation after both sides have been distributed correctly?

-4(x -2) = 5(3x -8)

•  -4x - 8 = 15x - 40

• -4x - 6 = 15x -3

• -4x + 8 = 15x -40

• -4x + 8 = 15x + 40

​Perimeter is adding all sides






Area is multiplying sides
