I believe the answer is B I pretty sure
So all the angles on one side should equal 180.
50+55= 105
180-105=75
12x+3=75
12x=72
12*6=72
x=6
The equation is ............... (it needed to be so many characters long)
390/1.5 = x - y
Step-by-step explanation:
focus(p) is on the x axis= -1
vertex=(0,0)
parabola equation----- (y-h)^2 =4p(x-k)
(h, k)=(0,0)
(y-0)^2 =4(-1)(x-0)

y^2 = -4x
that is the answer
