Write the equation of the parabola in vertex form. y = –x2 + 3

One of the same side angles of two parallel lines is 20° smaller than the other one. find the measures of these two angles.

What are the solution(s) to the quadratic equation x2 – 25 = 0? o x = 5 and x = -5ox=25 and x = -25o x = 125 and x = -125o no real solution

21 type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar. the solution set of n2 - 14n = -45 is { (separate the solutions with a comma)
