Question

classify each expression as a monomial;a binomial or trinomial a) 3a+4b-5c b) 2z² c) 2-4b+7 d) 1/7x+2/7y3/7z e) x-y f) -14x³ g) b²-4ac h) b-2b+3b-4b+5b​

Answer 1

Answer:

a. Trinomial

b. Monomial

c. Monomial

d. Trinomial

e. Binomial

f. Monomial

g. not confirm binomial

h. Monomial

Answer 2

Answer:

a) 3a + 4b - 5c

Trinomial because it has THREE ("tri") terms

b) 2z²

Monomial because it has only ONE term ("mono")

c) 2 - 4b + 7

Binomial because it has only TWO terms -- after you combine like terms

When you combine like terms, the expression becomes

- 4b + 9 <-- a binomial

d) 1/7x + 2/7y3/7z

This is probably a binomial but the terms don't have any grouping symbols

e) x - y

Binomial because it has two terms

f) -14x³

Monomial because it has only one term

g) b² - 4ac

Binomial because it has two terms

h) b - 2b + 3b - 4b + 5b​

Monomial because it has only one term after the like terms are combined

After you combine the like terms, the expression is:

3b <-- a monomial

Step-by-step explanation:

"Terms" are the expressions separated by + or - signs.

Any part that is separated by a plus sign or a minus sign is ONE TERM

If the numbers and letters are joined with multiplication or division, that is ONE TERM no matter how many numbers and letters are joined.
