To know which of the following expressions are polynomials, let us look at the definition of a polynomial:
Polynomial is derived from poly- (which means "many") and -nomial (meaning "term"), so it says "many terms".
For an instance: 
is a polynomial, but 
is not a polynomial because it contains single term only.
We must keep in mind that in polynomial it can have variables, constants, and exponents but it can never have division by a variable.
Now lets, look at the
since it has got one term it can not be a polynomial.
: it has got <em>more than one term</em> therefore, <em>it is a polynomial. </em>
: again it has got just one term so it is not a polynomial.
: Since it has got <em>more than one term</em>, so again<em> it is a polynomial. </em>
<span>(7x⁶ + 10x² - 10) + (3x⁶ - 6x³ + 4)
Put everything into order :)
7x⁶ + 3x⁶ - 6x</span>³ + 10x² - 10 + 4<span>
Add like terms.
(7x⁶ + 3x⁶) - 6x</span>³ + 10x² + (-10 + 4)<span>
Simplify.
10x⁶ - 6x</span>³ + 10x² - 6

The volume of a cone is V = 1/3 pi r^2 h
h = 8
pi = 3.14
V =471.24
r = ???
d = ???
471.24 = 3.14 * 8 * r^2
471.24 = 25.12 * r^2
471.24 / 25.12 = r^2
18.76 = r^2
r = sqrt(18.76)
r = 4.312
The diameter is 2*4.312 = 4.624 in. <<<<<==== answer.
Any number thats 8.5 or above
Answer:
794.1 ÷ 76.1= 10.4349.54
Round to the nearest whole number = 6
Round to the nearest tenth=5.6
Round to the nearest Hundredths=5.63
Round to the nearest Thousandth=5.635
