Arectangle has a perimeter of 30 inches.
what would be the new perimeter if the length and width of the rectangle were doubled in size?

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.

the answer is d. (1.2, -4.7) on edgn

hope this !
