Since the triangles are congruent your equation would be 2y+8=19
Solve for y
y=5.5
We can use quadratic formula to determine the roots of the given quadratic equation.
The quadratic formula is:
b = coefficient of x term = -11
a = coefficient of squared term = 2
c = constant term = 15
Using the values, we get:
So, the correct answer to this question are option B and D
Only the third one makes x=-1 true
