Answer:
x = 6 x = -7
Step-by-step explanation:
Subtract 12 from each side:
x^2 + x - 30 - 12 = 12 - 12
Simplify:
x^2 + x - 42 = 0
Solve with quadratic formula using both +/- after the first -1:
x = 
Simplify:
x = 6
x = -7
Answer:
I don't get it but in my opinion I would say it's 4
In a quadrilateral the angles should add up to 360 degrees.
