You have to draw a north line at A and measure the angle clockwise. So since B is due East of A, the bearing will be 090 degrees
That is true because a parallelogram has four sides.
The axis of symmety is the x value of the vertex
to find the x value of the vertex of ax^2+bx+c=0
x value=-b/2a
3x^2+bx+4=0
3/2=vertex
-b/2(3)=3/2
-b/6=3/2
times 6
-b=18/2
-b=9
times -1
b=-9
Be sure to keep places.
