Do, k = (6, 12) → (3, 6) the scale factor is 1/2 2 4

The scale factor of given coordinate

A is correct.

Step-by-step explanation:

We are given two coordinate O and K. The dilation with respect to origin.

For scale factor,

a is scale factor of coordinate.

If we divide new coordinate with old coordinate to get scale factor.

Hence, The scale factor of given coordinate

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
