<span>A, B, and C are polynomials, where A = n, B = 2n + 6, and C = n2 – 1. What is AB – C in simplest form? We want (n)(2n+6) - (n^2-1). (Please note: n^2 is correct, while n2 is not.)
Multiplying out the first term: 2n^2 + 6n
Subtracting n^2-1: - (n^2 -1)
----------------------
n^2 + 6n + 1 (answer) </span>
7 has no factors except ' 1 ' and itself, so it's a "prime" number.
If it were not a prime number, it would be a "composite" one instead.
You’re answer will be 99 because 12x99=1,188
Based on the calculations, Celine would earn a total of $65.00 assuming she delivered 10 packages.
<h3>What is a function?</h3>
A function can be defined as a mathematical expression which is used to define and represent the relationship that exists between two or more variable.
<u>Given the following function:</u>
y = 20.00 + 0.45(x)
In this exercise, you're required to determine Celine's weekly earnings based on the number of packages she delivered. However, the number of packages delivered by Celine wasn't shown, thus, we would assume a value for the purpose of an explanation:
Assuming x = 10 packages.
Substituting the value of x into the function, we have:
y = 20.00 + 0.45(10)
y = 20.00 + 45
y = $65.00.

Answer:
Step-by-step explanation:
Remember 
You are given the fraction 
First, multiply the numerator and the denominator by -2-3i:
This gives you 13 in denominator, now multiply two complex numbers in numerator:
Thus, the initial fraction is
