Answer:
The solutions are x = -7, 6.
Step-by-step explanation:
To find the solutions, move everything to one side of the equation so the equation is equal to 0. Then factor. Set the factors equal to 0 and solve for x.
![x^2 + x - 30 = 12\\x^2 + x -42=0\\(x+7)(x-6) = 0](https://tex.z-dn.net/?f=x%5E2%20%2B%20x%20-%2030%20%3D%2012%5C%5Cx%5E2%20%2B%20x%20-42%3D0%5C%5C%28x%2B7%29%28x-6%29%20%3D%200)
x+7 = 0
x = -7
and
x-6 = 0
x = 6
The solutions are x = -7, 6.
4(100)=400
400/1=400

Answer:
dude your teacher is on crack
Gabrielle's age is 3x (in which x is mikhail's age)
the sum is 56 so 3x+x=56
3x+x=56
4x=56
x=14
since x was mikhail's age, mikhail is 14 years old
