Entry: March 19,2010 ******************(Start)

Today we basically corrected our tests. There are a few questions people had trouble with, but I'm not completley sure if they were the ones.

(^2=Squared)

19. Write a simplified expression for the area of the following figure. What is the area of this figure?

--------------------------

20. Apply the distributive property to simplify: 2x(x-4)-3x(x-4)

=2x^2-8x-3x^2+12x (combine like-terms)

=2x^2-3x^2-8x+12x

=x^2+4x

--------------------------

21. A pool table is twice as long as it is wide. If the area of the pool table is 2.88m^2, what are the dimensions of the table.
