How do you find the perimeter of a rectangle with length l and width w?

Back

Perimeter = 2l + 2w.

Front

What is a polynomial?

Back

A polynomial is a mathematical expression that consists of variables, coefficients, and non-negative integer exponents.

Front

What is a binomial?

Back

A binomial is a polynomial with exactly two terms.

Front

What is a trinomial?

Back

A trinomial is a polynomial with exactly three terms.

Front

What is a monomial?

Back

A monomial is a polynomial with exactly one term.

Front

How do you combine like terms in a polynomial?

Back

You add or subtract the coefficients of terms that have the same variable raised to the same power.

Front

What is the degree of a polynomial?

Back

The degree of a polynomial is the highest power of the variable in the expression.

Front

What is the perimeter of a triangle with sides a, b, and c?

Back

Perimeter = a + b + c.

Front

If the perimeter of a rectangle is 20 and the length is 6, what is the width?

Back

Width = (Perimeter/2) - Length = (20/2) - 6 = 4.
