-20 + 9x = -17-20 + 17 = -9x-3 = -9x |: (-9)0.333... = xx = 0.333...
The given terms can be simplified to: 20x+20
9x2 - 28x + 20 = 9x2 - 18x - 10x + 20 = 9x(x - 2) - 10(x - 2) = (9x - 10)*(x - 2)
i thinking this answer should be -20
(9x)2 +9x/(45x)2 +81= 9+9x/86
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
-20 + 9x = -17-20 + 17 = -9x-3 = -9x |: (-9)0.333... = xx = 0.333...
The given terms can be simplified to: 20x+20
That factors to 4(9x + 5)
9x + 8 = 6x + 20(- 8 from both sides)9x = 6x + 12(- 6x from both sides)3x = 12(divide both sides by 3)x = 4
9x2 - 28x + 20 = 9x2 - 18x - 10x + 20 = 9x(x - 2) - 10(x - 2) = (9x - 10)*(x - 2)
i thinking this answer should be -20
11 + 9X
9x+3-25 = 4x-2 5x = 20 x = 4
(9x)2 +9x/(45x)2 +81= 9+9x/86
It is (x+4)(x+5) when factored
x=5.2
