Two positive integers are 3 units apart on a number line. their product is 108.

which equation can be used to solve for m, the greater integer?

m(m – 3) = 108

m(m + 3) = 108
(m + 3)(m – 3) = 108
(m – 12)(m – 9) = 108

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