Chen bought a basketball for $23, three baseball caps, and a pair of running shoes for $37. to find the total cost in dollars, he wrote 23 + 3d + 37 = 23 + 37 + 3d. which property does the equation show ?

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.
