Answer:
x-y=2.5,xy=21
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
One of the numbers is x.
The other number is y.
The difference between two numbers is 2.5
This means that x - y = 2.5
The product of those two numbers is 21.
This means that xy = 21.
So the two equations are: x-y=2.5,xy=21
Answer:
The result
.
is a polynomial.
Step-by-step explanation:
The first polynomial is
.
The second polynomial is 
The closure property of multiplication states that if we multiply two polynomials the result must be a polynomial.
The product of these two polynomials is :
.
We can see that the result is still a polynomial.
C is the correct answer for your question
C= 7 and 1 hope this helps!
X=34
34=34
45=45
But because OF this equation the answer is 34
