The length of a rectangle is 72 cm and the diagonal measures 75 cm. find the width and perimeter of the rectangle.

the image of (6, 9) under a dilation is (4, 6). the scale factor is

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
