i) -6w3+ 7w2 + 2w -11
ii) x5 + x9
iii) 4y3 - 3y + 2/y
iv) 3a5 -2a3 - 6a-1 + 15
v) j-1
vi) k6 - k4 + 3k - 2
help me !!!!!!!!!!! please.

Answer 1

a polynomial has no division by any variable term

descending order refers to whether the exponents on the variables get smaller from left to right

Answer 2

does the first expression have any division by a variable in it?

Answer 3

no

Answer 4

so it's a polynomial

do the exponents on the variables get smaller from left to right?

Answer 5

no bigger

Answer 6

I mean do they get smaller as you go to the right?
the leftmost exponent is 3
the next to the right is 2
etc.

so they are getting smaller as we go from left to right

Answer 7

yes iguess i mean idk

Answer 8

here is your expression

we call it an "expression" and not "equation" because it has no = sign in it.

I think you need to remember a little terminology...
