Write whether each expression is a monomial or a binomial. a. 3y b. (-9) + h c. wr+5wr d. - 7agh e. 2 f. k+12

Step-by-step explanation:

An expression with a single term a monomial, an expression with two terms is a binomial.

a. 3y - monomial

b. (-9) + h = - 9 + h = h - 9 - binomial

c. wr + 5wr = 1wr + 5wr = (1 + 5) wr = 6wr - monomial

d. - 7agh - monomial

e. 2 - monomial

f. k + 12 - binomial
