I think the answer might be B
W= l - 5 where w = width and l = length
area = 84 = l*w = l(l-5)
l(l-5) = 84
l^2 - 5l - 84 = 0
(l - 12)(l + 7) = 0
l = 12
length = 12 and width = 7
John is cool leave him alone pls what did he ever do
is the equivalent to "five to the third power"
It is D, because looking at a unit circle, 5pi/3 is about the same location as -sqrt3 which is approximately 1.4.
