Angel is going to drive from his house to City A without stopping. Angel's house is 200 miles from City A and after driving for 4 hours, he will be 40 miles away from City A. Write an equation for D, D, in terms of t, t, representing Angel's distance from City A tt hours after leaving his house

b

Step-by-step explanation:

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.
