3.1 to 3.3 Flashcard Review

Front

What is a constant in an algebraic expression?

Back

A constant is a fixed value that does not change. In the expression 2x - 3w - 12, -12 is a constant.

Front

What is a term in an algebraic expression?

Back

A term is a single mathematical expression that can be a number, a variable, or a combination of both. In the expression 2x - 3w - 12, -3w is a term.

Front

What is a coefficient in an algebraic expression?

Back

A coefficient is a numerical factor that multiplies a variable. In the term -3w, -3 is the coefficient.

Front

What does perimeter mean?

Back

Perimeter is the distance around a shape.

Front

How do you simplify the expression 7v + 2 + 12 + 2v?

Back

Combine like terms to get 9v + 14.

Front

What is the formula for the perimeter of a rectangle?

Back

The perimeter of a rectangle is calculated as P = 2(length + width).

Front

What is a variable in an algebraic expression?

Back

A variable is a symbol, often a letter, that represents an unknown value. In the expression 2x - 3w, x and w are variables.

Front

What is the difference between a term and a coefficient?

Back

A term is a part of an expression that can include numbers and variables, while a coefficient is the number that multiplies a variable within a term.

Front

What does it mean to simplify an expression?

Back

To simplify an expression means to combine like terms and reduce it to its simplest form.

Front

What is the expression for the perimeter of a shape with 3 sides of length x?

Back

The perimeter is represented as 3x.
