Fran has a plank of wood 4.65 meters long. she wants to cut it into pieces 0.85 meters long. how many pieces of wood that length can she cut from the plank?

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103

What is the area of the shaded sector?
