Evaluate the expression for x = 3, y=13 , and z = 5. 12x−3y/4x−z

State if the two triangles are congruent. if they are, state how you know?

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

Proportions in triangles solve for x
