In the figure above, rectangle R'S'T'Q' is a dilation of rectangle RSTQ. What is the scale factor of the dilation?

A.

Step-by-step explanation:

The scale factor of dilation is the ratio of the length of any of the corresponding sides of rectangle R'S'T'Q to rectangle PQRS.

R'S' = 3

RS = 15

Thus,

Scale factor =

Simplify

Scale factor =

i do not know this sorry : (

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
