GLPA031  area Zarea:ÖThe number of square units needed to cover a surface enclosed by a geometric figure. arithmetic sequenceÄarithmetic sequence:ÖA numerical pattern that increases or decreases at a constant rate or value. The difference between successive terms of the sequence is constant.ÖExample: 2, 5, 8, 11, 14, ...  coefficient,coefficient:ÖThe numerical factor of a term. common difference^common difference:ÖThe difference between any two consecutive terms in an arithmetic sequence. constant2constant:ÖA term that does not contain a variable. Distributive Property Distributive Property:ÖTo multiply a sum by a number, multiply each addend of the sum by the number outside the parentheses. For any numbers a, b, and c,Öa(b + c) = ab + ac andÖa(b - c) = ab - ac.ÖExample:Ö2(5 + 3) = (2 5) + (2 3)ÖandÖ2(5 - 3) = (2 5) - (2 3) equivalent equations<equivalent equations:ÖEquations that have the same solution. equivalent expressions½equivalent expressions:ÖExpressions that have the same value or that have the same mathematical meaning for all replacement values of their variables.ÖExamples:Ö3 + 2 = 10 - 5,Ö2x + 3x = 5x  formula›formula:ÖAn equation that states a rule for the relationship between certain quantities.ÖExample:ÖA = Är^2 is the formula for finding the area of a circle.  inverse operations¬inverse operations:ÖPairs of operations that undo each other. Examples:ÖAddition and subtraction are inverse operations. Multiplication and division are inverse operations.   like termsrlike terms:ÖTerms that contain the same variables raised to the same power.ÖExample:Ö5x^2 and 6x^2 are like terms.   perimeter9perimeter:ÖThe distance around a closed geometric figure.  sequence/sequence:ÖA set of numbers in a specific order. simplest form of an expression–simplest form of an expression:ÖAn expression is in simplest form when it is replaced by an equivalent expression having no like terms or parentheses. simplify/simplify:ÖWrite an expression in simplest form. term in an expression_term in an expression:ÖA number, a variable, or a product or quotient of numbers and variables. term in a sequence.term in a sequence:ÖEach number in a sequence.°-
