It is: 13-144 = -131
between 12 and 13 (144 and 169)
a = -4
144 + 13 + 20 = 177
52+122=25+144=169 and Sqrt169 = 13
The square root of 144 is 12, as 12 multiplied by 12 equals 144. The square root of 25 is 5, as 5 multiplied by 5 equals 25. Therefore, the sum of the square root of 144 and the square root of 25 is 12 + 5, which equals 17.
It is: 13-144 = -131
The square root of 144 (12*12) and the square root of 169 (13*13).
If the 13 was the long side (hypoteneuse), the other side would be the square root of 13²-5² = square root of 169-25 = square root of 144 = 12. (according to Pythagoras). If the 13 was a short side, the other is square root of 13² + 5² = square root of 169+25 = square root of 194, or about 13.93
