Tristan is building steps up to a deck that is 1 and 5/6 yards above the ground. the steps must be all the same height if you wants to make eight steps how high should he make each step

Let's work in inches. First, we convert 1 5/6 yards to inches.

1 5/6 yd * (36 inches)/(1 yd) = 11/6 * 36 in. = 66 in.

Now we divide the height by 8.

66 in./8 = 8.25 in.

8.25 inches

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

4+3x is the answer

hope you got it
