<span>a^3 - b^2 for a = 3 and b = 1/2
</span>3^3 - (1/2)^2
= 27 - 1/4
= 26 3/4
Y=mx+b
m=slope
perpendicular lines have slopes that multiply to get -1
the slopes are
for

and

, the slope are

since their product is -1, the lines are perpendicular

2- Therefore you have:
length=20 inches-</span>(20 inches x 3/8)<span>
