Find the lenth of a rectangle prism having a volume of 2,83.5 cubic meters, and height of 9 meters

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x

Which inequality is equivalent to -3x < -12? x < 4 , x < -4 , x > 4, x > -4

This is about circle theorems. someone asap : (
