If h = 7 then h squared = 49
1 squared plus 8 squared or 4 squared plus 7 squared
7^2 + 3^2 = 58
2 squared plus 2 x 3 = 10, 7 squared plus 7 x 2 = 63, 6 squared plus 6 x 5 = 66,8 squared plus 8 x 4 = 96 so 9 squared plus 9 x 7 = 81 + 63 = 144.
They are equal. 7 squared is 7 x 7, which equals 49. 6 x 7 = 42, plus another 7 = 49.
(9x2 + 7)(9x2 - 7) = 81x4 - 49
7 Squared is 49. 10 plus 49 is 59.
3 + 43 = 46 7 squared = 49 46 + 49 = 95
x=7
No. 7 squared plus 11 squared does not equal 15 squared.
6t2+17t+7 = (3t+7)(2t+1) when factored
No, it is not. For a right triangle, from the Pythagoraen theorem, 7 squared plus 9 squared does not equal 12 squared
