Find all possible solutions for x and y such that △ABC is congruent to △DEF. △ABC: sides of length 18, 25, and 5x − 3.
△DEF: sides of length 25, 22, and 5 − y.

△ABC ≅ △DEF when x is
and y is

The parabola y = x² - 4 opens: a.) up b.) down c.) right d.) left

Astudent draws two parabolas both parabolas cross the x axis at (-4,0) and (6,0) the y intercept of the first parabolas 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
