mosaic · Answer

4th degree implies the highest exponent is 4.
Trinomial implies three terms.

anonymous · Answer

i think its 2

anonymous · Answer

Look at the exponents.  The highest exponent must be 4.

anonymous · Answer

because you need 3 so that it become a trianomial and the highest power is 4

@vita955  which one do you think is correct?

miracrown · Answer

It should be B, it is 4th degree since 4 is the highest power
and it is a trinomial since it has three terms
