Find the unknown length of y.: (

We assume the slope is a constant, so the rise is proportional to the run.

... y/(4 ft) = (31 ft)/(3 ft)

... y = (4/3)·(31 ft)

... y = 41 1/3 ft = 41 ft 4 in

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
