What is the value for t 7t - 165 = 2104

t ≈ 324.14

Explanation:

   7t - 165 = 2104

⇒ 7t = 2104 + 165 = 2269

⇒ t = 2269 ÷ 7 ≈ 324.14

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
