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
25 + 144 = 169√169 = 13
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

84
the square root of 122+52 (144 + 25 = 169) which is 13.
The closest whole number square root is 12, since 12 x 12 = 144. The next closest are 13 x 13 = 169 or 11 x 11 = 121.
The square root of 13 = 3.605551275....
