Answer:
The scaled surface area of a square pyramid to the original surface area.
The scaled area of a triangle to the original area.
Step-by-step explanation:
Suppose that we have a cube with sidelength M.
if we rescale this measure with a scale factor 8, we get 8*M
Now, if previously the area of one side was of order M^2, with the rescaled measure the area will be something like (8*M)^2 = 64*M^2
This means that the ratio of the surfaces/areas will be 64.
(and will be the same for a pyramid, a rectangle, etc)
Then the correct options will be the ones related to surfaces, that are:
The scaled surface area of a square pyramid to the original surface area.
The scaled area of a triangle to the original area.
Answer: 
Step-by-step explanation:
88 can be rewritten as 8 x 10 and 8 can be rewritten as 
making a 2 come out of the root.
10 can be rewritten as 2 x 5.
2*2 can also be rewritten as 
making a 2 come out of the root.
We can't keep simplifying the root.
