In the diagram shown, CD = 7, DB = 8, AE = 5, mC =62° and AC is parallel to DE. Find the value of x and the length of AB

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.

One positive number is 9 more than twice another. if their product is 95, find the numbers

Solve the equation for x.3(6x - 1) = 12 i've tried doing the math and i can't find out what i'm doing wrong
