The first thing is to define each one:
Polynomial: expression made with constants, variables and exponents, which are combined using addition, subtraction and multiplication. Exponents can only be natural numbers and the polynomial cannot have an infinite number of terms.
Example:
This is a:
Degree: It is the exponent with the highest degree. If a monomial of those that are forming the polynomial has two unknowns, each with its exponent, these add up since we would be doing a multiplication of monomials.
Example:
The degree of this polynomial is 3 because it is the largest exponent.
Linear term coefficient: is the number that multiplies the variable with the highest exponent
Example:
In this case it is 5 because is the variable with the highest exponent
Constant term coefficient: is one that is found in a polynomial alone, that is, without multiplying the x or another unknown.
Example:
In this case it is 20 because it is the one found without multiplying any linear term (x)

This problem, as written, requires a bit of guessing regarding your intentions. My interpretation is that you want to do this division:
2
----------
1 6/7
If that's correct, here's what to do: rewrite 1 6/7 as 13/7 (an improper fraction).
Then divide:
2
-------- This is equivalent to the multiplication (2/1)(7/13) = 14/13 (answer)
13/7

Monday: 6 laps around a 0.25-mile track
Tuesday: 7 laps around a 0.25-mile track
Total miles jogged on both days.
0.25(6 + 7) = 0.25(13) = 3.25 miles
Mike jogged a total of 3.25 miles on Monday and Tuesday combined.
6+7=13
13*0.25= 3.25 miles
ANSWER= 3.25 miles

Step-by-step explanation:
Given that the manufacturer of cans of salted mixed nuts state that the ratio of peanuts to other nuts is 4 to 3.
So, ratio of peanuts to other nuts in a can = 4 : 3
Total number of nuts in a can = 464 nuts (i)
We need to find number of other nuts in a can.
Let number of peanuts be 4 k where k is a natural number.
Let number of other nuts be 3 k where k is a natural number.
Total number of nuts = 4 k + 3 k = 7 k (ii)
From (i) and (ii), we get 7 k = 464 which implies
So, number of other nuts in a can = ( approx. )
