Hi! I am practicing for the STAAR test, and I don't know how to do this question. If someone could get me started on how to do this or walk me through the steps, that would be helpful. :)

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400

In the diagram below? p is circumscribed about quadrilateral abcd. what is the value of x

Fast! find the length of cu. the triangles are similar. show your work.
