How do you show that two expressions are equal?
How do you show that two expressions are equal?
Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.
What is it called when two expressions have the same value?
Expressions that have the same value are called equivalent expressions.
What is a mathematical sentence that shows that two expressions are not equivalent?

What is a mathematical expression with two terms?
Binomial: An algebraic expression which consists of two non-zero terms is called a binomial. Examples of binomials: m + n is a binomial in two variables m and n. a2 + 2b is a binomial in two variables a and b.
Which term means two expressions are not equal?
inequality
An inequality is a mathematical relationship between two expressions and is represented using one of the following: ≤: “less than or equal to” <: “less than” ≠: “not equal to”
Which of the following expression is an equality between two expressions containing one or more variables?
In mathematics, an equation is a statement that asserts the equality of two expressions, which are connected by the equals sign “=”. Solving an equation containing variables consists of determining which values of the variables make the equality true.
What is a statement that compares two expressions that are not equal called?
An inequality is a mathematical relationship between two expressions and is represented using one of the following: ≤: “less than or equal to” <: “less than” ≠: “not equal to”
What is mathematical statement where one expression is not equal to another?
In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
What are mathematical sentences?
A mathematical sentence makes a statement about two expressions. The two expressions either use numbers, variables, or a combination of both. A mathematical sentence can also use symbols or words like equals, greater than, or less than.
What is an example of a mathematical expression?
An example of a mathematical expression with a variable is 2x + 3. All variables must have a coefficient, a number that is multiplied by the variable. In the expression 2x + 3, the coefficient of x is the number 2, and it means 2 times x plus 3.
