6t + 7 when t = -3 is 6*(-3) + 7 = -18 + 7 = -11
(t + 7)(t - 1)
7^2 + 3^2 = 58
They are equal. 7 squared is 7 x 7, which equals 49. 6 x 7 = 42, plus another 7 = 49.
3 + 43 = 46 7 squared = 49 46 + 49 = 95
6t + 7 when t = -3 is 6*(-3) + 7 = -18 + 7 = -11
(t + 7)(t - 1)
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
