The dog snored nine times. 1/3 of an hour is every 30 minute interval. 30 min + 30 min = 1 hour. Multiply this x3, and the answer is nine. A simpler way of thinking about this is 3 x 3 or 3 squared.
When they are the exact same, like carbon copies
A^2+b^2=c^2
24^2+b^2=26^2
576+b^2=676
-576. -576
b^2=100
