What are two major physical features of the earth that affect climate and weather? a. oceans and lakes c. lakes and rivers b. mountains and oceans d. mountains and deserts select the best answer from the choices provided a b c d

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

your answer is 20. hope this !
