Can someone please help me? I'm so confused thank you. :)

5x + 2 = 12 solve the following equation. then place the correct number in the box provided.

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (-4, 0) and (6,0). the y-intercept of thefirst parabola is (0, –12). the y-intercept of the second parabola is (0-24). what is the positive difference between the avalues for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth.

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