Answer: Answer: −9±√−255/ 24

Step-by-step explanation:

12a2+9a+7=0

a=12, b=9, c=7

12a^2+9a+7=0

a=12, b=9, c=7.

−b±√b2−4ac/ 2a

−(9)±√(9)2−4(12)(7)/ 2(12)

In a parallelogram, the opposite angles will be congruent to each other.


In this parallelogram, angles B and C are congruent, and angles A and D are congruent.


We will work on angles B and C first. Set the two angles to equal each other:


12x + 6 = 6x + 66


Subtract 6 from both sides:


12x = 6x + 60


Subtract 6x from both sides:


6x = 60


Divide both sides by 6 to get x by itself:


\boxed{x = 10}


x will equal 10.


Set angles A and D to equal each other:


54 = 3y


Divide both sides by 3 to get y by itself:


\boxed{y = 18}


y will equal 18.


The x and y values that make this quadrilateral a parallelogram will be x = 10, and y = 18.
