Find the distance between each pair of points. simply the radicals no decimals (-12, 3) (-3, 15)

15

Step-by-step explanation:

distance formula = square root of difference of y-values subtracted by difference of x-values

d = = 15

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.

i think 1: 2
