Use Demoivres Theorem to find (-sqrt3 + i)^6
A. -64

Solve the equation using the given values: x= -2.5; y= -7.51. 2xy + 2x²

Plz ( true - false) all triangles have interior angles whose measure sum to 90.

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y > 2x + 3y is less than negative 3 over 2 times x minus 4part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points)part b: is the point (â’4, 6) included in the solution area for the system? justify your answer mathematically. (4 points)
