Answer: No, Ariel should have added 9^2 and 12^2 and compared that to 15^2.
Explanation:
Ariel completed a work to show that a triangle whether a triangle with side lengths of 9, 15, and 12 form a right triangle.
Ariel added 9 squared + 15 squared = 12 squared. 81 + 225 = 144 and concluded that 306 is not-equal to 144 and hence, it is not a right angle triangle.
To know whether it's a right angle triangle, we had the square of the two lowest figures together if it will be equal to the square of the largest figure which is called the hypotenuse.
9 squared + 12 squared =
81 + 144 = 225
15 squared= 15 × 15 = 225
So it's a right angle triangle since
9^2 + 12^2 = 15^2
The cattle boom led to economic prosperity for the rise, growth, and development of new towns in the west resulting to the development of service businesses, for example, hotels, salons, e.t.c. The cattle were bought cheap and resold at high prices which allowed the ranchers to make a lot of money (profit).
1.(False) 2.(True). hope this helps although might want to proof read on the second question doesn't quit make sense.
