Rico is making 18punch for 18 people. how much punch should rico make if each person will drink 1/6 gallon of punch?

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

Find the number of real number solutions for the equation. x2 + 5x + 7 = 0 0 cannot be determined 1 2

How to do this , and can some one explain
