ChAlLaNgE

Pretend you want to fit a perfectly shaped circular rug into your perfectly square room. All you know right now is that the radius of the rug is "r" feet long. 1) Find the area of the rug, 2) the area of the room and then 3) the area of the room that won't be covered by the rug. (hint -draw a picture!)

1.The area of the rug is 3.14rsquared
2.The area of the room is 4rsquared ♥
3.The area of the room that wont be covered is 14% of it.

new gas prices

The lowest gas price is $1.97. Now with the new gas prices, it would only cost me $25 dollars to fill my car up. The equation I used was 250 miles per week/22 mpgx$2.20= $25. It used to cost me 40 dollars but now it costs me 25 so i am now saving myself 15 dollars.

I learned from reading those article that for every one dollar decline in the price of oil saves the U.S consumers one billion dollars. Also, I learned that gas prices haven't dropped this much until the 1980's! 60% of the worlds gasoline is being used by people going to work. That is what I learned from that article.

Polynomials

Then, POST about something new you learned AND something that is now clearer for you. After you have posted, leave me a comment on this assignment so I know you are done! :)

I have learned what a binomial a trinomial a monomial and a polynomial was. A binomial is an equation with 2 terms. A trinomial is an equation with 3 term A polynomial is an equation with many terms and a monomials is an equation with 1 term. Something that is more clear to me is how you combines like terms and exponents. I learned when you are multiplying two polynomials with different exponents you add the to exponents to simplify it.
