### September 10th 2008

Today in class, Mrs. Ingram showed us how to divide polynomials and what not. Here is an example that she gave us in class:

1.) HINT: When dividing, subtract the exponents

She went through a couple of example with us, then Mrs. Ingram told us to do questions 1 though 12. If you don't have your booklet w/ you. Here are the questions.

1. Divide: (x² + 6x + 5) ÷ (x + 1)

2. Divide: (x² + x - 20) ÷ (x + 5)

3. Divide: (x³ + 3x² + 3x + 1) ÷ (x + 1)

4. Divide: (x³ + 6x² + 2x +12) ÷ (x + 6)

5. Divide: (3x² + 12x + 12) ÷ (3x + 6)

6. Divide: 8x² - 2x - 15 / 4x - 5

7. If the area of a rectangle is x² + 9x + 18 units² and the length is x + 6 units, what is the width?

8. If x = 3, find the value of 6x - 1 + 3x°.

9. Solve the equation: 4 - 3(x - 2) = 7x + 6

10. Solve the equation: x/3 + 2 = 6 - x/6

11. The three doors were side by side, labeled with three consecutive numbers. Could this be the place? Thor stared at them intently. Little Peter handed him a notepad. He multiplied the largest of the three numbers by ten and he subtracted twice the smallest number. The result was a disappointing 124. What were the three numbers on the doors?

12. Triangle ABC has a right angle at C. If AB = 6cm and AC = 4cm,
a. find the length of BC
b. find the measure of angle A to the nearest degree.
