Question

Which statement about a dilation with a scale factor of 3 is true?

A.Three is added to each side in the pre-image to find the corresponding side length in the image.
B.Three is subtracted from each side in the pre-image to find the corresponding side length in the image.
C.Each side in the pre-image is multiplied by three to find the corresponding side length in the image.
D. Each side in the pre-image is divided by three to find the corresponding side length in the image.

Answer 1

Three is added to each side in the pre-image to find the corresponding side length in the image.

Three is subtracted from each side in the pre-image to find the corresponding side length in the image.

✅ Each side in the pre-image is multiplied by three to find the corresponding side length in the image.

Each side in the pre-image is divided by three to find the corresponding side length in the image.

Explanation:

FOR SHORT it is C

Answer 2

C. Each side in the pre-image is multiplied by three to find the corresponding side length in the image.

Explanation:

The scale factor multiplies every linear dimension in the pre-image. It is the ratio of image dimensions to pre-image dimensions.

So, for a scale factor of 3, each side in the pre-image is multiplied by 3.
