Factoring quadratics intro
The rectangle below has an area of x2
152 + 56 square meters and a length of 2 – 7 meters.
What expression represents the width of the rectangle?
27
Width
x2 - 152 + 56
Width =
meters

Anyone know? will mark brainliest if you're correct!

What are the solutions of the system? y = x^2 + 2x +3y = 4x - 2a. (-1, -6) and (-3, -14)b. (-1, 10) and (3, -6)c. no solutiond. (-1, -6) and (3, 10)

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.
