You are planning to build a regular octagonal shaped swimming pool in the backyard of your house, which is a rectangular shape with length of 30m and width of 20m. The pool will have a pathway around it with the width of 1m and the width of the wall will be 15cm. 1) How many octagons will there be? 2) What is the area of the octagon that needs to be dug out? 3) What is the area of the pathway around the pool? 4) What is the area of the wall portion of the pool?

40 points for your own answer! highschool math! george is folding a piece of paper to make an origami figure. each time he folds the paper, the thickness of the paper is doubled. the paper starts out flat, with a thickness of 1 millimeter. a. write a list of six ordered pairs showing the output as the thickness of the paper when the input is the number of times it is folded. explain how you came up with your ordered pairs. b. is this relation a function? explain why or why not using the ordered pairs you came up with in part a.

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
