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 - 3

*b*) + (2 + 2

*b*)

b) (8

*k*+ 3

*m*) + (2

*k*- 5

*m*)

c) (3

*a*+ 2

*b*) - (

*a*+ 3

*b*)

d) 3(2

*x*^2

*y*- 3

*xy*+ 7) + (

*xy*- 3

*x*^2

*y*- 2)

e)

*x*(4

*x*^2 + 5

*x*) -2

*x*^2(5

*x*^2 - 2

*x*)

f) (1/2

*x*+ 1/3

*y*) - (3/2

*x*+ 2/3

*y*+ 5) + (7/2

*x*+ 1/5

*y*+ 4) *

2.

**Find the sum of 7**

*x*^4*y*^3 - 3*xy*and 6*x*^5 - 5*xy*.3.

**Wanda's age is (4**

*x*+ 3*y*+ 6) and her daughter's age is (2*x*-*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**.
