9. Bob is building a shelf. He wants it to fit into a space that's 20 feet long. The 20 feet of the shelf will be split into sections. The first section of the shelf is to be 5 feet, and the
other sections shall be 3 feet long each. How many sections will there be in the shelf?

9 x 8 divided by (5-3)=36

okay..i will pick 8!

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
