Which are steps that could be used to solve 0 = 9(x2 + 6x) – 18 by completing the square? check all that apply.
18 +81 = 9(x2 + 6x +9)
18+9 = 9(x2 + 6x +9)
18+ 36 = 9(x2 + 6x + 36)
11 = (x + 3)2
1342 = (x + 6)2
799 = (x + 3)2

(05.03 mc) part a: explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of the equation 4x = 2x−2. (4 points) part b: make tables to find the solution to 4x = 2x−2. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 4x = 2x−2 graphically? (2 points)
