Over 3 yr, lucia saved $550, $600, and $650 from baby-sitting jobs. the polynomial 550x3 + 600x2 + 650x represents her savings, with interest. after 3 yr. the annual interest rate equals x - 1. find the interest needed so that she will have $2000 after 3 yr.

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
