triangles pqr and lmn are similar. if qr = 6 - and mn=9 what simularity transformation maps pqr to lmn

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:

false

inverse variation is not exponential

answer is  

a.

5.56

hope you get this right.
