1 Dr. Fowler CCM1A EXAM REVIEW 01

2 Pythagorean Theorem leg hypotenuse The hypotenuse is always the longest side of a right triangle and is always opposite the right angle.

3 Using a 2 + b 2 = c 2  Looking for length of the hypotenuse  a 2 + b 2 = c 2  15 2 + 20 2 = c 2  225 + 400 = c 2  625 = c 2

4 Using a 2 + b 2 = c 2  Find the Leg  a 2 + b 2 = c 2  6 2 + b 2 = 10 2  36 + b 2 = 100  -36 -36  b 2 = 64  b = 8

5 Ex 1 Find the distance between the points P(-3, 2) and Q (-2, 4). Work inside parentheses Do powers before doing the addition!!!!!!

6 + 4 + 4 3 · · 3 x = 36 12 – 4 = 8 2) Solve 1.Draw “the river” 2.Add 4 to both sides 3.Simplify 4.Clear the fraction - Multiply both sides by 3 5.Simplify 6.Check your answer D U ÷ 3 - 4 + 4 · 3

7 3) Solve d – 4 = 6 + 4 + 4 d = 10 1.Draw “the river” 2.Clear the fraction - Multiply both sides by 2 3.Simplify 4.Add 4 to both sides 5.Simplify 6.Check your answer D U - 4 ÷ 2 · 2 + 4

8 http://www.mathslideshows.com Solve With x’s on Both Sides

9 http://www.mathslideshows.com 13 = 4(3x – 7) + 5 13 = 12x- 28 + 5 13 = 12x - 23 +23 +23 36 = 12x__ ___ 12 12 3 = x 13 = 4(3 3 – 7) +5 13 = 4(9 - 7) + 5 13 = 8 + 5 13 = 13 13 = 4(2) + 5 Solve With The Distributive Property

10 http://www.mathslideshows.com Solve With The Distributive Property

11 http://www.mathslideshows.com Solve With The Distributive Property Challenging One!

12 Excellent Job !!! Well Done

13 Stop Notes Do Worksheet
