What is the length of NO?
N= (7,-4)
O=(-7,-4)

Evaluate the expression for the given value of the variable 7a - 4a for a =8

When solving this problem: 3025/5.5 = a/90.75 you get 49912.5 which would be the length of one of the sides of a square when the area is only 90.75 inches. is that answer correct, why, and how is it possible?
