Adding and Subtracting Monomials with Geometric Application

Front

What is a monomial?

Back

A monomial is a polynomial with only one term, which can be a constant, a variable, or a product of constants and variables raised to non-negative integer powers.

How do you add monomials?

Back

To add monomials, combine like terms by adding their coefficients while keeping the variable part the same.

What are like terms?

Back

Like terms are terms that have the same variable(s) raised to the same power(s). For example, 3x^2 and 5x^2 are like terms.

What is the perimeter of triangle ABC if it is given as 7x + 2y units?

Back

The perimeter is the sum of all sides, so if one side is missing, you can express it as the total perimeter minus the sum of the other two sides.
