A man travels 20 km by car from Town P to Town Q at an average speed of x km/h. He finds that the time of the journey would be shortened by 12 minutes if he increases his speed by 5 km/h. Find the value of x.​

Solve the system of equations. y= 2x y= x^2 - 15

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
