x^2 + 18 = 9x
x^2 - 9x + 18 = 0
(x )(x )
Since 6 * 3 = 18 and 6 + 3 = 9,
(x 3)(x 6)
Since the 18 is positive, the factors are either both positive or both negative. Since the 9 is negative, they must both be negative.

If x equals 10 and y equals 10 then 9x plus 8y equals?
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
What is 9x plus 27 equals -81?
9x+27 = -81 9x = -81-27 9x = -108 x = -12
X plus 20 plus 10x equals 20 plus 9x x equals?
x + 20 + 10x = 20 + 9x 11x + 20 = 20 + 9x Subtract 20 from both sides: 11x = 9x Subtract 9x from both sides: 2x = 0 Divide both sides by 2: x = 0
What is the slope of -9x plus 6y equals 54?
-9x+6y = 54 6y = 9x+54 y = 1.5x+9 slope = 1.5
If x equals 6 and y equals 3 then 9x plus 8y equals?
9x + 8y = (9 x 6) + (8 x 3) = 54 + 24 = 78
What is x if 9X plus 18 equals 180?
9x+18 = 180 9x = 180-18 9x = 162 x = 18
