You cant just ask for it you need to earn it

Answer 5

A. 3m^2n - 2m/n + 1/n
B. 2mn/5 - m2/4 + 4m^5
C. 4m^3/n^2 - 3mn^5 + sq8
D. 7mn + 3m/2 + 5n/4

Answer 6

well, it's not a polynomial if there is a negative exponent, variable exponent, a variable in the denominator, or no square roots of variable. Examples:
`negative exponent`: \[f(x)=2x^-3+4x-7\]
`variable exponent`: \[f(x)=4^x\]
`variable denominator`:\[f(x)=2x^2-\frac{ 7 }{ x }+4\]
`square roots`: \[f(x)= \sqrt{x}\]

Now, from your answer choices, we can get rid of A because there are variables as the denominator. Then we can also get rid of c because of the sq8, which is not allowed, as i said above. So then, from B and D, which do you think is correct? It may help is you use the `Equation` feature and actually write the two options out so you can see it better.

Answer 7

D

Answer 8

i'd agree with you there. do you understand why it is D?
