What types of volcanoes are formed at spreading centers

Rift volcanoes.

Rift volcanoes are formed at spreading centers when magma rises into the gap between diverging plates.

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
