Answer: When two polynomials are multiplied, the product is always a
polynomial.
Step-by-step explanation:
The only true property for polynomials is the third options because when you do multiply polynomials, you can only get a polynomial.
For instance;
Multiply (5x – 6y) by (7x – 4y)
= (5x – 6y)(7x – 4y)
= 35x² - 20xy - 42xy + 24y²
= 35x² - 62xy + 24y²
The result is a polynomial.
The rest of the options will not always yield polynomials.
We can apply the following properties of radicals:
Then, we have:
Therefore, the choice that is equivalent to the given product is:
Answer:
AB= 3
CD= 3.5
Step-by-step explanation:
Slope formula:
m= (y{2} - y{1}) / (x{2} -x(1})
So
AB's slope equals (4-1)/ (2-1)
m= 3/1
m=3
And
CD's slope equals (6- {-1})/(5-3)
m= 7/2
m=3.5
Hope this helps!
