Coefficient

A numerical or constant factor that multiplies a variable in an algebraic expression, indicating how many times the variable is counted.

Variable

A symbol used to represent an unknown value in mathematical expressions and equations.

Where is the coefficient in '“5x”?

In the expression "5x", the coefficient is the number 5, which multiplies the variable x.

Where is the coefficient from “x”?

In the expression "x", there is no visible coefficient, but it is understood to be 1, because there is always a coefficient, indicating that the variable x is counted once.

What is the product of 5x and 3 + x if x = 4?

The product of 5x and 3 + x is 140.

What is the value of X?

The value of x is unidentified as it is a variable.

What is the difference between an expression and an equation?

An expression does not show equality, while an equation does show equality, typically using an equals sign (=).

What is a constant in an algebraic expression?

A constant is a fixed value that does not change, represented by a number in an algebraic expression.

What is a term in an algebraic expression?

A term is a single mathematical entity in an expression, which can be a constant, variable, or the product of constants and variables.

What does it mean to simplify an algebraic expression?

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

What are like terms in an algebraic expression?

Like terms are terms that have the same variable raised to the same power, allowing them to be combined.

What is the coefficient in the expression "3y + 5"?

In the expression "3y + 5", the coefficient is 3, which multiplies the variable y.

How do you evaluate an algebraic expression?

To evaluate an algebraic expression, substitute the values of the variables into the expression and perform the necessary operations.
