Which of the following towns could be described as urban? A. Halifax, pop. 9,000 B. Quincy, pop. 100,000 C. Adams, pop. 8,000 D. Ayer, pop. 6,000

The answer is A. Hope this helped you

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
