The answer is the last option (Option D), which is:
D. 25
The explanation is shown below:
1. You have that:
(a ± b)^2=a^2 <span>± 2ab + b^2
2. The expression given in the problem is:
</span><span>x^2-10x+n
Where x^2=a and 2ab=10x
2b=10
b=10/2
b=5
3. Therefore, you have:
b^2=5
b^2=25
b^2=n
n=25</span>

The answer is combining like tems
Answer:
$513.34
Step-by-step explanation:
Mr. DeLuca used his debit card twice, each time for $27.50. This is a total of $55 spent.
$27.50 × 2 = $55
You now have to subtract the money spent from his bank balance.
$568.34 - $55 = $513.34
$513.34 was left in his bank account.
Standard form of the polynomial is 
.
Degree of the polynomial is 7.
Solution:
Given polynomial:
<u>To write this polynomial in standard form:</u>
Standard form of the polynomial is writing x from highest power to lowest power.
Therefore, standard form of the polynomial is
<u>Degree of the polynomial:</u>
The highest power of x in the polynomial is the degree of the polynomial.
Here, the highest power is 7.
Hence the degree of the polynomial is 7.
