Given:

The shown represents the difference between the squares
So, the product of the polynomials will be as follows:

So, the answer will be:
This simplifies to:

The degree of our simplified answer is 4
Answer:

Step-by-step explanation:
Combinatorial explanation:
The n balls have to be arranged in n positions and the only distinction is where are the black and where white balls are.
We can choose the position of black balls in
ways, therefore, white ones are on the remaining positions.
Using binomial we can have explanation written below:
The balls can be arranged in n! possible permutations.
To be precise one particular arrangement includes
permutations. Since r black balls can be permuted in r! ways and white balls in (n-r)! different orders.
So basically it yields,
permutations.
So the actual amount is,

Um what blocks? We need the full problem please
Hello!
Let's write this as an equation.
74x=66
Now let's solve by dividing both sides by 74.
x≈0.89
Now we multiply by 100 to make it a percent.
0.89(100)= 89
Therefore, our answer is 89%
I hope this helps!
