4.An artist has been commissioned to make a stained glass window in the shape of a regular octagon. The octagon must fit inside an 

 square space. Determine the length of each side of the octagon. Round to the nearest hundredth of an inch.

5. Lorene plans to make several open-topped boxes in which to carry plants. She makes the boxes from rectangular sheets of cardboard from which she cuts out 6-in squares from each corner. The length of the original piece of cardboard is 12in more than the width. If the volume of the box is 798 in3, determine the dimensions of the original piece of cardboard.

6.Barbara drives between Miami, Florida, and West Palm Beach, Florida. She drives 45 mi in clear weather and then encounters a thunderstorm for the last 40 mi. She drives 20 mph slower through the thunderstorm than she does in clear weather. If the total time for the trip is 1.75 h , determine her speed driving in nice weather and her speed driving in thunderstorm.
