**Let’s Get Ready**To Play Some . . .**J**E O P A R D Y JEOPARDY JEOPARDY JEOPARDY JEOPARDY JEOPARDY**Jeopardy Board**Final Jeopardy**Add and Subtract Polynomials - 100**(2x2 + 5x) + (7x2 + 3x + 11) Board Answer**Add and Subtract Polynomials - 100**(2x2 + 5x) + (7x2 + 3x + 11) Since you are adding the two polynomials the parentheses mean nothing 2x2 + 5x + 7x2 + 3x + 11 Combine like terms 9x2 + 8x + 11 Board**Add and Subtract Polynomials - 200**(x2 + 8x – 11) + (x3 + 3x2 + 11) Board Answer**Add and Subtract Polynomials - 200**(x2 + 8x – 11) + (x3 + 3x2 + 11) Since you are adding the two polynomials the parentheses mean nothing x2 + 8x – 11 + x3 + 3x2 + 11 Combine like terms x3 + 4x2 + 8x + 0 x3 + 4x2 + 8x Board**Add and Subtract Polynomials - 300**(2x2 – 5x3) – (7x3 – 2x2 + 11) Board Answer**Add and Subtract Polynomials - 300**These signs must change (2x2 – 5x3) – (7x3 – 2x2 + 11) Since you are subtracting the two polynomials the parentheses are very important 2x2 – 5x3 – 7x3 + 2x2 – 11 Combine like terms -12x3 + 4x2 – 11 Board**Add and Subtract Polynomials - 400**3(9x2 – 5x) – (x3 – 2x2 + x – 4) Board Answer**Add and Subtract Polynomials - 400**Distribute the 3 These signs must change 3(9x2 – 5x) – (x3 – 2x2 + x – 4) Since you are subtracting the two polynomials and multiplying the first by 3, the parentheses are very important 27x2 – 15x – x3 + 2x2 – x + 4 Combine like terms -x3 + 29x2 – 16x + 4 Board**Add and Subtract Polynomials - 500**(x + 3) + (7x2 – 5x) – (3x3 – x2 – 4x – 6) Board Answer**Add and Subtract Polynomials - 500**These signs must change (x + 3) + (7x2 – 5x) – (3x3 – x2 – 4x – 6) x + 3 + 7x2 – 5x – 3x3 + x2 + 4x + 6 Since you are adding the first two polynomials the parentheses mean nothing. Combine like terms -3x3 + 8x2 + 0x + 9 -3x3 + 8x2 + 9 However, you are subtracting the third so the parentheses are very important Board**Exponent Rules - 100**(x3)(x2) Board Answer**Exponent Rules - 100**(x3)(x2) x3 = x x x x2 = x x (x3)(x2) = x x x x x = x5 Board**Exponent Rules - 200**(5x5)(7x7) Board Answer**Exponent Rules - 200**(5x5)(7x7) 5x5 = 5 x x x x x 7x7 = 7 x x x x x x x (5x5)(7x7) = 5 x x x x x 7 x x x x x x x= 35x12 Board**Exponent Rules - 300**Board Answer**Exponent Rules - 300**1 2 Board**Exponent Rules - 400**Board Answer**Exponent Rules - 400**Option 1 Option 2 Board**Exponent Rules - 500**Board Answer**Exponent Rules - 500**Board**Scientific Notation - 100**Rewrite in scientific notation 23,000,000 Board Answer**Scientific Notation - 100**Rewrite in scientific notation 23,000,000 The decimal is at the end of a whole number 23 000 000 = 2.3 x 107 In scientific notation the decimal goes after the first digit. You need to know how many place values you have to move the decimal Board**Scientific Notation - 200**Rewrite in scientific notation 0.000345 Board Answer**Scientific Notation - 200**Rewrite in scientific notation 0.000345 You can see where the decimal is 0.000345 = 3.45 x 10-4 In scientific notation the decimal goes after the first digit. You need to know how many place values you have to move the decimal Board**Scientific Notation - 300**Rewrite in standard form 8.76 x 104 Board Answer**Scientific Notation - 300**Rewrite in standard form 8.76 x 104 8.76 00 = 87,600 Move the decimal 4 places Add two zeros Board**Scientific Notation - 400**Rewrite in standard form 2.0406 x 10-5 Board Answer**Scientific Notation - 400**Rewrite in standard form 2.0406 x 10-5 0000 2.0406 = 0.000020406 Move the decimal 5 places Add four zeros Board**Scientific Notation - 500**Multiply, write in scientific notation (2.6 x 105) (3.1 x 106) Board Answer**Scientific Notation - 500**Multiply, write in scientific notation (2.6 x 105) (3.1 x 106) Multiply the numbers and add the exponents (2.6 x 105) (3.1 x 106) = 8.06 x 10 11 Board**Area - 100**What is the product when you multiply 4x3y2 and 3x4y Board Answer**Area - 100**What is the product when you multiply 4x3y2 and 3x4y 4x3y2 = 4 x x x y y 3x4y= 3 x x x x y 12x7y3 4x3y23x4y = 4 x x x y y 3 x x x x y Board**Area - 200**Find the area of the rectangle 7x4 5x3 Board Answer**Area - 200**Find the area of the rectangle A = L W A = 7x4 5x3 7x4 A = 7xxxx 5xxx A = 35x7 5x3 Board**Area - 300**Find the area of the triangle 6x3 3x2y5 Board Answer**Area - 300**Find the area of the triangle 6x3 3x2y5 Board**Area - 400**Find the length of the rectangle 3x4 Area = 24x6 L Board Answer**Area - 400**Find the length of the rectangle Fill in the blank 8x2 3x4 = 24x6 3x4 Area = 24x6 L = 8x2 Board**Area - 500**Find the base of the triangle 6x A = 3x2y5 b Board Answer**Area - 500**Find the base of the triangle Fill in the blank 6x xy5 A = 3x2y5 b Board**Final Jeopardy Category**Area of a rectangle Board**Final Jeopardy Question**Find the area of the rectangle 5x2 Perimeter is 40x2 Answer**Final Jeopardy Question**Find the area of the rectangle 5x2 + 5x2 = 10x2 15x2 5x2 5x2 So the other 2 sides add up to 30x2 15x2 Area = length times width Perimeter is 40x2 Area = 15x2 5x2 If the perimeter is 40x2, what is the length? Area = 75x4
