Answer 1

C.

Explanation:

this is correct on ed-genuity, hope this helps! :)

Answer 2

C) [ 0 12 12 0]

[ 0 0 12 6]

Explanation:

The vertices of the given rectangle is (0, 0), (4, 0), (4, 4) and (0, 2)

The scale factor is 3.

We have to multiply each coordinate by 3, we get

(0, 0), (12, 0), (12, 12) and (0, 6)

When we write it in matrix form, we get

[ 0 12 12 0]

[ 0 0 12 6]

The answer is C.

Thank you.
