Please help!! I'm confused

30

Step-by-step explanation:

1. distribute the 5 on both pair of parenthesis...you will get 5z+20+10-5z

2. group the variables so when we group it we will get 5z-5z and 20+10

3. the 5z-5z cancels out so what we have left is 20+10 therefore it gives up the answer 30

ummm seems that u didnt post the attachement !

"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.
