The expression r - 5√r+r² is a polynomial.
<h3>What is a polynomial?</h3>
Mathematical expressions called polynomials have one variable and many exponents.
The algebraic expression must have all of its exponents be non-negative integers in order for it to be a polynomial. As a general rule, an algebraic expression isn't a polynomial if it contains a radical.
No part of an algebraic expression should be - Variables' square roots. variable powers that are fractional. variable powers that are negative. variables in any fraction's denominator.
Exponents, variables, and constants make up a polynomial. The amount of terms a polynomial has determines its name.
Polynomials come in various varieties. Monomial, binomial, and trinomial, respectively.
The idea of the graph of a polynomial equation was first introduced by René Descartes in La géometrie, published in 1637.

Answer:
179.50 
Step-by-step explanation:
The equation for volume of a cone is:

The radius is half of the diameter so r= 3.5 in
The height is 4 times the radius so h=14

V= 179.50 
The answer in simplest form would be 2 and 3 fifths gallons of gas.
Answer:
-191.10
Step-by-step explanation:
When you divide 56/23 you get 2.4, 2.4 is negative.
Multiply 2.4 6 times
&
2.4^6.
You get -191.10.
I am probably wrong but I tried.
HAVE NO IDEA! this takes alot of thinking to figure it out
