whats the options

Answer 2

mb yo,this is the Q:

Four polynomials are shown below:

A. 3 - 7x5 + x2
B. 5x3 + 5 - 3x
C. 3x + 2x3 - x2 + 6 + 2x
D. 3x3 - 5 + 2x5 + x + 2x2

Which of the above polynomials is a 5th degree trinomial?

Polynomial A

Polynomial B

Polynomial C

Polynomial D

Answer 3

is it b..

Answer 4

no degree is the highest power which option has a number raised to the 5th power

Answer 5

d

Answer 6

@YanaSidlinskiy

Answer 16

Welcome!!:D

Answer 17

hmm think i should go redo this test then i thought i just wasnt getting it didnt know they asked for a specific nomial

Answer 18

We all need too:)
5x^3 + 5 - 3x is of degree 3
largest exponent = degree (for single variable polynomials)
