x + 12x - 45 = 0 13x - 45 = 0 13x = -45 x = - 45/13 = -3.462 (rounded)
-45 over 9 = -5 -5 plus 5 = 0 QED -45 over (9 plus 5) is a different matter and = -3.2143.
-6x + 0 = 45 Simplifies to: -6x = 45. By dividing both sides by -6, we arrive at the final: x = -45/6
x2 + 14x + 45 = 0 => x2 + 9x + 5x + 45 = 0 => x(x + 9) + 5(x + 9) = 0 (x + 9)(x + 5) = 0 so that x = -5 or x = -9
The roots are: x = -5 and x = -9
correct anser is C ; y=-45
It is a quartic equation in the variable x.
It isn't. 45-45 = 0.It isn't. 45-45 = 0.It isn't. 45-45 = 0.It isn't. 45-45 = 0.
The answer to the equation 9 plus 5 times 0 equals 45. This was taught in 5 grade math.
Yes because if 1+0=1 than 0 plus b equals b
Multiply both sides by 9, giving y + 45 = 0 so y = -45
A=0 b=0 c=0
