Find the missing length. △XYZ maps to △MNO with the transformation (x, y) arrowright (4x, 4y).

If XY = 3, what is the length of MN?

The length of MN is

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

y/x of point b= y/x of point a
