Find the x coordinate of the vertex of the parabola sketched in the figure below ? PLEASE HELP!

Complex numbers multiply √-4 * √-25 and show all intermediate steps. alternative notation is sqrt(-4) * sqrt(-25).

Aadc is formed by reflecting aabc across line segment ac, as shown in the figure. if the length of ac is 4 units, the area of aadc is square units.

Ofin . (2,4) (2,1) a. y= 2 b. x= 2 c. x= -2 d. y= 2x
