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:
The equivalent equation is ![p^2 + 18 = 9p](https://tex.z-dn.net/?f=p%5E2%20%2B%2018%20%3D%209p)
Step-by-step explanation:
p is given by the following relation:
![p = x^2 - 2](https://tex.z-dn.net/?f=p%20%3D%20x%5E2%20-%202)
And we are given the following equation:
![(x^2 - 2)^2 + 18 = 9x^2 - 18](https://tex.z-dn.net/?f=%28x%5E2%20-%202%29%5E2%20%2B%2018%20%3D%209x%5E2%20-%2018)
On the right side, we can simplify. So
![(x^2 - 2)^2 + 18 = 9(x^2 - 2)](https://tex.z-dn.net/?f=%28x%5E2%20-%202%29%5E2%20%2B%2018%20%3D%209%28x%5E2%20-%202%29)
Replacing
by p, the equation is:
![p^2 + 18 = 9p](https://tex.z-dn.net/?f=p%5E2%20%2B%2018%20%3D%209p)
