Hey there! :)


-(3x)² + 3 = -6


Simplify.


-(9x²) + 3 = -6


Simplify.


-9x² + 3 = -6


Subtract 3 from both sides.


-9x² = -6 - 3


Simplify.


-9x² = -9


Divide -9 from both sides.


-9x² ÷ -9 = -9 ÷ -9


Simplify.


x² = 1


So, x = 1 OR x = -1


~Hope I helped!~

In the diagram below, the top of each stair is parallel to the floor. What is the value of y?
Semmy [17]
The value of y would be C) 38 degrees because if the floor and the top of the stair are parallel, then that makes the diagonal line a transversal, therefore the 38 degree angle and y are alternate interior angles.
