Answer:
C and E
Step-by-step explanation:
Examples of binomials (two terms) :
9a - 5
3x + 6y
-4t + 2
Examples of monomials (one term) :
6x
10z
4a
Examples of trinomials (three terms) :
7y - 3x + 4
8x + 7 - 2a
4x + 9y + 5
(There can also be exponents and fractions in any kind: binomial, monomial, or trinomial.)
