• both 3x and 7 are terms

• 7 is a constant term

• 3 is the coefficient of 3x

• True

• False

• True

• False

• True

• False

We say that we (a)   an expression when we write it as an equivalent expression with as few terms as possible, and write each term as simply as possible

• True

• False
