Express 5. in the form of a geometric series.

5.555 = 5.1 + 0.05 + 0.005

          = 5.5 + 0.05 + 0.05(.1)

            = 5.5 + 0.05/(1-.1)

            =5.5+0.05/.9

            =5.5 + 5/90

            = 5.5+1/18

            =55/10 + 1/18

            = 495/90 + 5/90

            =500/90

            = 50/9

            = 5 5/9

Step 2: (x + 4)(x + 2) = 8

Step-by-step explanation:

x2 + 6x + 8 = 0

x2 + 4x + 2x + 8 = 0

x(x + 4) + 2(x + 4) = 0

(x + 2)(x + 4) = 0
