1 8.3 Random fact of the day: McDonald's is the world's largest distributor of toys!

2  Using your knowledge of exponents and algebra, simplify this expression:

3  So how about this one?

4

5  The ratio of a vacation destination’s area to its miles of coast line is often used by travel agents to attract tourists.

6  For example: New Hampshire has a total area of 8,970 square miles but only 13 miles of coast line

7  The ratio of a vacation destination’s area to its miles of coast line is often used by travel agents to attract tourists.  For example: New Hampshire has a total area of 8,970 square miles but only 13 miles of coast line

8  The ratio of a vacation destination’s area to its miles of coast line is often used by travel agents to attract tourists.  For example: the area of Greece has a ratio of 10 to 9.28. In other words, 92.8% of Greece’s land touches an ocean. How else can we write this?

9  Lets say the country of Shepaugylvania has an area of  Square miles

10  Compare this area to the amount of ocean-front Shepaugylvania has; represented by (c-6)miles

11  So we’re back to square one….

12

13

14  Solve the following problem:

15  Recalling the methods used to solve that problem, how might you solve this?

16

17

18  So the ratio is expressed as (c+5) to (c-6)  How does this compare to the original dimensions of Shepaugylvania?

19  So the ratio is expressed as (c+5) to (c-6)  How does this compare to the original dimensions of Shepaugylvania? What happens when you FOIL (c+5)(c-6)?

20  What are some rules for dividing polynomials the “long division” way?

21  Lets look at our first expression:

22  Try another: *video

23  Try another:

25 Tell me something good

26 Do work
