WILL GIVE BRAINLIEST Explain how you find the scale factor using 2-3 sentences or showing each step. Explain using the ratio of the image length to the pre-image length.

Answer/Step-by-step explanation:

The scale factor = the ratio of the corresponding sides of the image and the preimage.

That is, A'B'/AB = B'C'/BC

The preimage is the smaller figure, given as ABCD.

AB = 3 - 1 = 2 units

BC = 4 - 1 = 3 units

The image is the larger figure, given as A'B'C'D'.

A'B' = 9 - 5 = 4 units

B'C' = 7 - 1 = 6 units

Scale factor =

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
