There isn't much to talk about for Friday's class .
We had a substitute for the day ; Mr. Kuropatwa wasn't in class .
But he left us a worksheet to work on . It was still review of polynomials and such .
That's all we did for class .
I'm quite sure everyone got the worksheet but if you somehow misplaced it , here are the questions :

1. Simplify each of the expressions below.

a) (a - 3b) + (2 + 2b)

b) (8k + 3m) + (2k - 5m)

c) (3a + 2b) - (a + 3b)

d) 3(2x^2y - 3xy + 7) + (xy - 3x^2y - 2)

e) x(4x^2 + 5x) -2x^2(5x^2 - 2x)

f) (1/2x + 1/3y) - (3/2x + 2/3y + 5) + (7/2x + 1/5y + 4) *

2. Find the sum of 7x^4y^3 - 3xy and 6x^5 - 5xy .

3. Wanda's age is (4x + 3y + 6) and her daughter's age is (2x - y - 4). Find the difference of their ages , expressing your answer in terms of x and y .




* The reason why I starred " f) " was because that was the one that I had difficulty with . I'm sure there are others in the class who had difficulty with this question as well . If you understood how to do it , could you please explain and help us understand .


Monday's scribe will be Jessica .
