(x+9)(x+4)
This is a quadratic equation question which will have two answers: 2x2+42 = x2+13x 2x2-x2-13x+42 = 0 x2-13x+42 = 0 Factorising the equation gives you: (x-6)(x-7) = 0 Therefore: x = 6 or x = 7
X = 12
There can be no answer because the question contains an expression, not an equation or inequality.
If -14 is the y intercept then it is: y = -1/13x -14
7+3w-13x
x2 + 13x + 12 = (x + 1)(x + 12)

There can be no answer because the question contains an expression, not an equation or inequality.
If -14 is the y intercept then it is: y = -1/13x -14
7+3w-13x
The equation then would be y = 13x
6.50 to the nearest hundredth (4.685 & 1.815)

13x 32 plus 5x can be expressed mathematically as 173x/32.
The equation y = 13x is in the form "y = mx + b" (in this case, b is zero). Therefore, the equation is linear.
12x2+13x-35 = (4x-5)(3x+7) 12x2 + 13x- 35 let's find two factors of -420 (12*-35) whose sum is 13, which are 28 and -15 (12x + 28)(12x - 15) now simplify by 4 and 3 (3x + 7)(4x - 5)
