Answer:
I think it's either C or A
QR and QS are perpendicular bisectors of the isosceles triangle XYX
so QR= QS
1/2 x + 2 = x - 10
1/2 x - x = - 10 - 2
-1/2x = - 12
x = (-12) * (-2/1)
x = 24
QS = 24 - 10
QS = 14
Answer
C . 14
Answer:
the vertex is ( 3 , 3)
Symetric axis‘s equation: x = 3
Step-by-step explanation:
Let‘s name the function ” f ”
f(x) = y = 2x² - 12x + 21
the vertex has coordinates of ( -b/2a , f(-b/2a) )
-b/2a = 12/2(2) = 12/4 = 3
f(-b/2a) = f(3) = 2(3)² - 12(3) + 21 = 3
then the vertex is ( 3 , 3)
the symetric axis has the equation :
x = -b/2a
then
The expression is not equivalent to 
.
