Find the cube roots of unity by using each method stated.
a. solve the polynomial equation x^3 = 1 algebraically.
b. use the polar form z^3 = r(cos(theta) + sin( and find the modulus and argument of z.
c. solve (a + bi)^3 = 1 by expanding (aa + bi)^3 and setting it equal to 1 + 0i.

Quick translate "x is 12 units from 20" into an equation. what are the values of x being described? if you can answer any of my other questions that'd be great too

The perimeter of a rectangle is 42 inches. if the width of the rectangle is 6 inches, what is the length

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
