An equilateral triangle has a perimeter of 15x + 24. What is the length of one side of the triangle?

After being rearranged and simplified, which of the following equations could be solved using the quadratic formula? check all that apply. a. 9% + 3x2 = 14 + x-1 b. -x+ + 4x + 7 = -32-9 c. 5x + 4 = 3x4 - 2 d. 2x2 + x2 + x = 30

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
