Answer:
x = √(w(w+z))
Step-by-step explanation:
The idea with a right-triangle figure of this sort is that all of the triangles are similar. Here, x is the short side of ∆ABC, and the hypotenuse of ∆BDC. This suggests you want to write a similarity statement involving the short side and hypotenuse.
BC/AC = DC/BC . . . . . short side/hypotenuse
BC² = AC·DC . . . . . . cross multiply
x² = (w+z)w . . . . . . substitute letter values
Taking the square root and rearranging to the form of the applicable answer choice, this is ...

-2.875_____-1.125
so
-2.875 < -1.1225
cause -2 is greater than -1
Let’s simplify!
y = 6(x - 2)² - 3
y = 6(x - 2)(x - 2) - 3
y = 6(x² - 2x - 2x + 4) - 3
y = 6(x² - 4x + 4) - 3
y = 6x² - 24x + 24 - 3
y = 6x² - 24x + 21
