Not much happened during class today, although we did continue with Exercise 1 from #10 and on. If for some reason you don't have the questions, here they are:

11- If x = 2 and y = -3, find the values for the following:

A) x + y (x + y) B) 2x² + 3xy

12- Solve these equations:

A) 3 (x - 2) = 4 - (x - 2) B) x [over] 3 + 1 = x - 4

13- Simplify the following expressions:

A) (3x²)(5x³) B) (3x^4)² C) 12x^5 [over] 3x²

14- How many triangles are in this diagram?

15- The area of a triangle is A. If the base is of length b, express the length of the altitude in terms of A and b.

16- The solution to the equation 2x + 3 = 3x + [ink blot] is x= -8 What number is under the ink blot?

17- Find the value of x.

18- Find the value of x. Express your answer to one decimal place.

19- Use trigonometry to find the value of x. Give the answer to two decimal places.

20- Use trigonometry to find x. Give the answer to two decimal places.
