21x + 9 = 180 21x = 180 - 9 21x = 171 x = 171/21 x = 8.143
The rate of change, with respect to x, is -21.
Add like terms together: 21x-21
It is 21x.
20x + 5 - 20 = 21x + 4 -x = 4 + 15 x = -19
21x + 9 = 180 21x = 180 - 9 21x = 171 x = 171/21 x = 8.143
The rate of change, with respect to x, is -21.
Add like terms together: 21x-21
2x2 + 21x + 49 = (2x + 7)(x + 7)
2x2+21x+49 = (2x+7)(x+7)
It is 21x.
(7x+2)(2y-1)
21x+452 = 32-84x 21x+84x = 32-452 105x = -420 x = -4
45
i hope you mean (2x^2 + 21x + 49) you cant solve it its already in its lowest possible form
20x + 5 - 20 = 21x + 4 -x = 4 + 15 x = -19
3x+21x+9x=33x. Break it apart. The factor of x is x and the factors of 33 are 3 and 11. Therefore, the factors of 3x+21x+9x are 3, 11, and x.
