A furniture delivery store advertises free delivery up to a 50 mile radius from the store. When the store’s location is placed on a map, its coordinates are (10, 20). Part a: Write an equation that represents the free delivery area.
Part b: Does a customer who lives at coordinates (20, -40) qualify for free delivery?
Part c: Explain how you know.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
