The answer to the problem of 12X plus 13 equals 9 is x equals -1/3.

12x+6y=9 - 1 4x+2y=0 - 2 y=-2x sub y= -2x into 1, 12x+6(-2x)=9 12x-12x=9 0=9 thus, no solution.

(2x + 3)(2x + 3)

1 and 3

2x + 3 = -92x = -12x = -6

3x multiplied by (12x plus 9) is:3x(12x + 9)= (3x * 12x) + (3x * 9)= 36x2 + 27x

It is: 122-4*(9*-2) = 216

few errors in your title: 2 plus 4 = 6 6 plus 9 = 15 10 plus 25 = 35 18 + 81 = 99

9n+9=81 9n=72 n=8

4x2 - 12x + 9 = 5; whence, 2x - 3 = ±√5, and 2x = 3 ±√5. Therefore, x = ½ (3 ±√5).
