Terms, constants, coefficients

Front

What is a constant in an algebraic expression?

Back

A constant is a fixed value that does not change, represented by a number without a variable.

Front

Identify the coefficients in the expression 8n - 7 + 9n + 5.

Back

The coefficients are 8 and 9, which are the numerical factors of the variable n.

Front

How do you combine like terms in the expression 8n - 7 + 9n + 5?

Back

Combine the coefficients of n (8 + 9) and the constants (-7 + 5) to simplify to 17n - 2.

Front

What is the difference between a term and a coefficient?

Back

A term is a single mathematical expression (like 8n), while a coefficient is the numerical factor in a term (like 8 in 8n).

Front

What is the value of the expression -7 + 5?

Back

The value is -2.

Front

How do you identify constants in an expression?

Back

Constants are the terms in the expression that do not contain any variables.
