1 Name: Class: Chapter 1 Symmetry and Surface Area REMEMBER TO SHOW ALL WORK! P.G John says to rotate a rectangle 90 you have to move the rectangle ¼ clockwise. Brianna says to rotate a rectangle 90 you have to reflect it horizontally. Who is right? Why?

2 Chapter 2 Rational Numbers P.G ` 7.

3 Chapter 3 Powers and Exponents P.G Sunvir says that 5 2 is the same as 5 x Saad says that 5 2 is the same as 5 x Who is right? Why? Show your work. 1 What does a 0 equals to.

4 Chapter 4 Scale Factors and Similarity P.G In the model, every cm equals 12 km in real life. If the distance between two places measures 1 m on the model, what is the distance in real life?

5 Chapter 5 Introduction to Polynomials P.G Aaron said that in the monomial 3x 2, 3 is the constant. Joanna quickly countered his argument and said that 3 was the co-efficient. Who is right? Why? Solve. a) (4x 2 + 2x -1) + (8x 2-3x +5) b) (81x x 0 9) (9 15x 2 )

6 Chapter 6 Linear Relations P.G

7 Chapter 7 Multiplying & Dividing Polynomials P.G ` Harman says that in the equation 6/2(1+2) =? The answer is 9. Asrar says the answer is Who is right? Why? (Remember BEDMAS) 7.

8 Chapter 8 Solving Linear Equations P.G Nay-Yar bought 4 bags of peas. When she got home, she noticed one of the bags were punctured and she lost 20 peas. When she poured out all the peas, there were a total of 120. How many peas were suppose to be in the punctured bag?

9 Chapter 9 Linear Inequalities P.G Tamiza has box of mangos. She knows the box will contain at least 15 mangos, but not more than 2 Write an inequality to express this. Amar says that the statement 2x > -10, x > - Ripndeep says that x < - Who is right? Why? Express x > -2 in two different ways. Solve the following inequality. 4x + 20 > 8x + 60, and then graph it on a number line

10 Chapter 10 Circle Geometry P.G

11 Chapter 11 Data Analysis P.G Lexus and Ghazel decide to take a survey on student s favourite academic subject. Lexus decides to ask every grade nine female student. Ghazel decides to ask every 3 rd student that enters the school. Which survey will be least bias? Why?

12 Rectangular Prism SA = 2B + Ph SA = 2(lw) + (2l + 2w) h Formulas V = lwh Cube SA = 2B + Ph SA = 2(s 2 ) + (4s)s = 6s 2 V = Bh V = s 3 SA = 2B + ph SA = 2(π r 2 ) + (2πr)h V = Bh V = π r 2 h Cylinder Pythagorean Theorem a 2 +b 2 =c 2

13 Triangle Area = ½b h b = base h = vertical height Rectangle Area = w h w = width h = height Square Area = a 2 a = length of side Circle Area = πr 2 Circumference=2πr r = radius Pi(π) Pi = 14 Perimeter Length of all sides added together
