1. Find all complex numbers z such that |z-1|=|z+3|=|z-i|, if i is the square root of -1. I got to the part where you graph the equations, but got stuck. 2. Find all cube roots of 8i. I know there are 3 answers, but I am stuck.

Given: LM ∥ KN, KL ∥ NM, LP = h­1 = 5, MQ = h2 = 6, PKLMN = 42 Find: AKLMN

I need help please, how can I get a graphing calculator?

Ans is 81pi
