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
3^2+x^2=8^2
9+x^2=64
x^2 = 64-9=55
The answer is B
