Answer:
s/8 = -8
s = - 64
Step-by-step explanation:
Solution
s/8 - 12 = -20 Add 12 to both sides
s/8 -12+ 12 = -20+ 12 Combine
s/8 = - 8 Multiply both sides by 8
8*s/8 = - 8*8
s = - 64
Okay so this is just step by step hope this helps you.

I don't know if this is exactly what you are looking for but here is the lateral surface area
Answer:
scale factor (k) is 2
Step-by-step explanation:
Look at W and W'. W is (-2, -1), but W' says (-4, -2). 2 x 2 is 4 and 1 x 2 is 2. Both coordinates were multiplied by 2. The same goes for all the other vertices, so it would be k = 2.
