Section 1

Question Answer
Module 6 - Algebraic ExpressionAn expression that contains at least one variable. x+ 8 4(m-b)
Distributive PropertyThe 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.
EquationA mathematical sentence that shows that two expression are equivalent. x +4 =7 6+ 1 = 20-3
FactorA number that is multiplied by another number to get a product. 7 is the factor of 21 since 7 *3= 21.
SolutionIn an equation, the value for the variable that makes the equation true.
VariableA symbol used to represent a quantity that can change. 2x + 3, x is the variable.

DegreeThe unit of measure for angels or temperature.
DimensionThe length, width, or height of a figure.
PolygonA closed plane figure formed by the three or more line segments that intersect only at their endpoints (vertices).
RatioA 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.

SquareA rectangle with four congruent sides.
TrapeziodA quadrilateral with exactly one pair of parallel sides.
TriangleA three-sided polygon.
VolumeThe numbers of cubic units needed to fill a given space.
CircumferenceThe distance around a circle.
Composite FiguresA 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.
DiameterA line segment that passes through the center of a circle and has endpoints on the circle, or the length of that segment.
RadiusA line segment with one endpoint at the center of the circle and the other endpoint on the circle, or the length of that segment.
