72/18 by S/16

s=64

Step-by-step explanation:

so we would multiply s by 18 and 16 by 72

so 18s=1152

we can then divide both sides by 18 to simplify

s=64

"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.
