yes, they are all proportional
<u>Answer:</u>
<u>Step-by-step explanation:</u>
We are given the following expression and we are to find its product:
Here, we need to recall the the product rule according to which the exponents are added when you multiply two powers that have the same base.
So here the powers of 
and 
will be added to their powers to give:
= 
=
Therefore, the product of the given expression is .
Answer:
A. 20x² + y and B. 20x² are polynomials.
Step-by-step explanation:
Let's review each of the expressions given to define which are polynomials:
A. 20x² + y
It's a polynomial because all of the variables have integer exponents that are positive
.
B. 20x²
It's a polynomial because the variable of this monomial have integer exponent that is positive
.
C. 20x² + y ^1/2
It's not a polynomial because a term has a fraction exponent (y ^1/2).
D. 20x²/y
It's not a polynomial because a term has a negative exponent (y ^-1) and there is a variable in the denominator of a fraction.
