Suppose we had a device that allowed us to see Earth's interior. If we looked at a typical region of the mantle, what would we see happening

i'm sure the answer you are looking for would be

a. an ice age

hope this contact me if this didn't or you need with more answers : )

the answer would be the third option, "no, ariel should have added 9^2 and 12^2 and compared that to 15^2."

this is found through the pythagorean theorem, which is a^2 + b^2 = c^2.

this is the correct way of solving the problem:

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225
