What is the answer to the equation, 27x^3 -8?

Triangle xyz has vertices x(1,3), y(0,0)

What value of x is in the solution set of 4x – 12 s 16 + 8x?

Which of the expressions (on the photo document i inserted) together represent all solutions to the following equation? 8cos(12x)+4=-4 *the answer should be in degrees.* > i would like for someone to explain the process to find the solutions for this.
