Algebraic Expressions Practice

What is an algebraic expression?

• A mathematical phrase that can include numbers, variables, and operation symbols, such as @@3x + 5@@.

• A type of equation that only contains numbers.

• A graphical representation of a function.

• A statement that can be true or false.

What is the difference between an expression and an equation?

• An expression is a combination of numbers, variables, and operations without an equality sign, while an equation states that two expressions are equal, indicated by an equality sign (e.g., @@2x + 3 = 7@@).

• An expression is a statement that can be true or false, while an equation is a mathematical sentence that shows the relationship between two expressions.

• An expression can only contain numbers, while an equation can contain both numbers and variables.

• An expression is always equal to zero, while an equation can have any value.

What is a coefficient?

• A numerical factor in a term of an algebraic expression, such as in @@4x@@ where the coefficient is 4.

• A variable that represents an unknown value in an equation.

• A constant term that does not change in an algebraic expression.

• A mathematical operation that combines two or more numbers.

• 1

• 2

• 3

• 4

What does it mean to simplify an expression?

• To combine like terms and reduce it to its simplest form, such as @@3x + 2x - 5@@ simplifying to @@5x - 5@@.

• To make an expression more complex by adding more terms.

• To change the variables in an expression to different letters.

• To evaluate the expression to find its numerical value.

What is the constant in the expression @@3x + 4@@?

• 3

• 4

• x

• 0

What is the product of two terms?

• The result of adding them together.

• The result of multiplying them together.

• The result of subtracting them from each other.

• The result of dividing them.

How many terms are in the expression @@2m + 3y - 7@@?

• 2

• 3

• 4

• 1

• 1

What are like terms?

• Terms that have different variables raised to the same power.

• Terms that have the same variable raised to the same power.

• Terms that are always positive numbers.

• Terms that can be added together regardless of their variables.
