X = √63
2^2 + 3^2 = 4 + 9 = 13
52
it would be 1 fourth multiplied by quanity d squared plus 3d plus 9 (1/4)(d2 + 3d + 4)
7(3y-2)-(-4y+9)
9 - 4 =5, 5+36= 41
3
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.
(p+9)(p+6)
The given expression can be simplified to: 8x squared +9
x=9 squared
6 squared is 36. 36 plus 3 is 39
(x - 6)(x + 9)
57
It is: 36 plus 121 = 157
6(3r^2 - 14r + 3) and (2c + 1)(c - 9)
That is 9 + 16 + 5 which is 30.
