Answer 2

Well a polynomial is an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s). So does this help you?

Answer 3

2 Answers are wrong that i see what do you think they are?

Answer 4

somewhat

Answer 5

Ok what answers look wrong based upon the definition?

Answer 6

a

Answer 7

Correct, Now what?

Answer 8

i know that dividing by a variable is a no no

Answer 9

so b aswell

Answer 10

Why do you say that? Because it is over something? Because your questions does not state they cannot be divided does it? :)

Answer 11

no it doesn't

Answer 12

By the way it can be done if you evaluate or just divide by 1, as the variable represents 1

Answer 13

So does C or D have more than two terms? Or just two terms?

Answer 14

yea i'm not sure how can you tell if their are mutiple terms

Answer 15

Ok well 3x is a term 3 is not

Answer 16

x is a term

sqrt6 is not

Answer 17

\[\sqrt{6}\] is not

Answer 18

so a term has to include a variable?

Answer 19

Well it can't be just a number. And from what i have had to do on FLVS yes.

Answer 20

2/x is a term and so is 3x. So do C/D have 2 terms or more?

Answer 21

2 terms?

Answer 22

Ok here let me give you a definition of a term. I was wrong about the numbers, however the division signs are a seperator -> Term: arts of an expression or series separated by + or – signs, or the parts of a sequence separated by commas.

Answer 23

so 2 then

Answer 24

Division signs are not a seperator*

Answer 25

Yes exactly c and d are 2 terms.

Answer 26

Where a polynomial is more than two algebraic terms.

Answer 27

so i'd say c?

Answer 29

Maybe that will help you, it has some examples.

Answer 30

C and D to me look wrong but if your gut feeling says C go with it :)!

Answer 31

this is what i read http://www.mathsisfun.com/algebra/polynomials.html

Answer 32

K let me see.

Answer 33

Ah that gives me a different way of seeing this, Now i agree with C

Answer 34

Wait no i don't

Answer 35

or it can be d

Answer 36

it says sqrtx is not

Answer 37

since it doesn't have a variable in it

Answer 38

so it's d then

Answer 39

Yes because it does not say that a variable itself cannot be a negative. Nice job!

Answer 40

i have one more question mind helping?

Answer 41

Uh depends is it the same type of question?

Answer 42

sorta

Answer 43

Is it Trinomials,Binomials, or Monomials?

Answer 44

Answer 45

So what you need to do is find the perimeter.

Answer 46

And from there we can determine if it is a polynomial or not.

Answer 47

so add all of them together

Answer 48

Yes let me see real quick

Answer 49

What is the final answer? :)!

Answer 50

i got 9x-8

Answer 51

Correct

Answer 52

By the way do you have any answer choices?

Answer 53

yay thanks so much helping dude :D

Answer 54

Wait you know if it is a polynomial then?

Answer 55

Just making sure :)!

Answer 56

And sure thing.

Answer 57

pretty sure

Answer 58

Okay good luck! :)

Answer 59

it's a polynomial doesn't break any rules

Answer 60

thanks again

Answer 61

Sure thing :)!
