Ways to spot if an expression is not a polynomial:
1) If there is a negative exponent
2) If there is division by a variable
3) If the power is something other than a non-negative integer
If any of these conditions exist, the expression will not be a polynomial. Now consider the options. Option A has negative exponent, Option B involves division by a variable and Option D has a exponent which is not a number.
So, from the given options, option C is the only polynomial
Answer:
The midpoint M is (5,7)
Step-by-step explanation:

U(8,9)
V(2,5)
m = [(8+2)/2 , (9+5)/2]
= [(10/2) , (14/2)]
= (5,7)
(Correct me if i am wrong)
Answer:
-256
Step-by-step explanation:
First let’s establish a few things, The first car can travel 300 miles with 20 gallons of gas, if 14 gallons of gas costs 49.49 then for ever gallon of gas Sam is paying 3 dollars and 53.5 cents. That means for 20 gallons, Sam will need around 71$ for the entire trip if he uses the first car.
The notation per capita simply means that the number is
divided by the total population. Therefore the number of McDonald’s per capita
in Canada 2013 is:
McDonald’s per capita = 1427 / 35,160,000
<span>McDonald’s per capita = 4.06 x 10^-5</span>
