Give a polynomial of degree 3 that has zeros of 18, 10i, and -10i and has a value of -3434 when x = 1. Write the polynomial in standard form

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.

Labc is reflected across x = 1 and y = -3. what are the coordinates of the reflection image of a after both reflections?

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
