THIS IS URGENT PLEASE GAW DAMMIT ;-; Using the graph, determine the coordinates of the x-intercepts of the parabola.

The width of a rectangle is 20 units. can the perimeter p of the rectangle be 64 units when its length x is 11 units? no, because p = 2x + 2(20) no, because p ≠ 2x + 2(20) yes, because p ≠ 2x + 2(20) yes, because p = 2x + 2(20)

Could somebody me with this radical simplification?

Solve this problem! extra ! 3025/5.5 = a/90.75
