10x+7 = 5x+32 10x-5x = 32-7 5x = 25 x = 5
10x - 25 = 4x + 510x - 4x = 25 + 56x = 30x = 5
25
(x + 5)2
(x+5)^2 and therefore x = -5
x2 + 10x = 0 x2 + 10x + 25 = 25 (x + 5)2 = 25 x + 5 = +-5 x1 = 0 x2 =10
10x+5y = 25 5y = -10x+25 y = -2x+5 Therefore: the slope is -2 and the intercept is 5
depends on what x is
10x+7 = 5x+32 10x-5x = 32-7 5x = 25 x = 5
10x - 25 = 4x + 510x - 4x = 25 + 56x = 30x = 5
If you mean:0 = 800 - 10x + 25 * 20 = 800-10x+25*210x = 800+50x = 8,50 = 800 - 10x + 25 * x * 20 = 800 - 10x + 50x-800 = 40x-50 = x

25
It is: 4x squared
x2 - 10x + 25 = 0(x - 5)(x - 5) = 0x - 5 = 0x = 5
Twenty-Five x2 + 10x = 8 x2 + 10x + 25 = 8 + 25 (x + 5)2 = 33
They are: (4x-5)(2x+5)
