## Section 1

Question | Answer |
---|---|

Module 6 - Algebraic Expression | An expression that contains at least one variable. x+ 8 4(m-b) |

Distributive Property | The property that states if you multiply a sum by a number, you will get the same results if you multiply each addend by that number and then add the products. |

Equation | A mathematical sentence that shows that two expression are equivalent. x +4 =7 6+ 1 = 20-3 |

Factor | A number that is multiplied by another number to get a product. 7 is the factor of 21 since 7 *3= 21. |

Solution | In an equation, the value for the variable that makes the equation true. |

Variable | A symbol used to represent a quantity that can change. 2x + 3, x is the variable. |

## Section 2

Question | Answer |

Module 7- Algebraic Expression | An expression that contains at least one variable. x + 8 4(m-b). |

Coefficient | The number that is multiplied by the variable in an algebraic expression. 5 is the coefficient is 5b. |

Constant | A value that does not change. 3,0, pi. |

Inequality | A mathematical sentence that shows the relationship between quantities that are equivalent. 5 <8 5x +2 >12 |

Variable | A symbol used to represent a quantity that can change. 2x +3 , x is the variable. |

## Section 3

Question | Answer |
---|---|

Module 8 - Angle | A figure formed by two rays with common end point called the vortex. |

Degree | The unit of measure for angels or temperature. |

Dimension | The length, width, or height of a figure. |

Polygon | A closed plane figure formed by the three or more line segments that intersect only at their endpoints (vertices). |

Ratio | A comparison of two quantities by division. 12 to 25 , 12 :25, 12/25 |

Adjacent Angles | Angles in the same plane that have a common vertex and a common side. |

Complementary Angles | Two angles whose measures add to 90`. |

Congruent Angles | Angels that have the same measure. |

## Section 4

Question | Answer |
---|---|

Module 9 - Area | The number of square units needed to cover a given surface. |

Parallelogram | A quadrilateral with two pairs of parallel sides. |

Perimeter | The distance around a polygon. |

Prism | A polyhedron that has two congruent, polygon- shaped bases and other face that are all parallelograms. |

Rectangle | A parallelogram with four right angles. |

Square | A rectangle with four congruent sides. |

Trapeziod | A quadrilateral with exactly one pair of parallel sides. |

Triangle | A three-sided polygon. |

Volume | The numbers of cubic units needed to fill a given space. |

Circumference | The distance around a circle. |

Composite Figures | A plane figure made up of triangles, rectangles, trapezoids, circles, and other simple shapes, or a three-dimensional figure made up pf prisms, cones, pyramids, cylinders, and other simple three-dimensional figures. |

Diameter | A line segment that passes through the center of a circle and has endpoints on the circle, or the length of that segment. |

Radius | A line segment with one endpoint at the center of the circle and the other endpoint on the circle, or the length of that segment. |
