Answer:

15.6

Step-by-step explanation:

We need to use Pythagorean theorem:

hypotenuse ² =( leg 1)² + (leg 2)²

Hypotenuse is 18 ft.

leg 1 = 9 ft.

18² = 9² + (leg2)²

(leg 2)² = 243

(leg 2) = +√243 ≈ 15.6 (ft)

What is the sum of the 12th square number and the 9th square number
Inessa [10]

Answer: 225

Step-by-step explanation:

<u>What is a square number</u>?

A square number is a product of a number times itself

So, the 12th square number would be 12 * 12, or 12²

The 9th square number would be 9 * 9, or 9²

The equation would be 12² + 9²

So:

12² + 9²

= 144 + 81

= 225

So, the answer is 225
