Answer:
The completely factored polynomial is:
⇒ 
Step-by-step explanation:
Given polynomial:
To factor the given polynomial completely.
Solution:
In order to factor the given polynomial, we will find the greatest common factor of the terms and then factor them out by dividing the term by its G.C.F.
The factors can be listed as:
From the factors listed the GCF can be given as = 
GCF = 
Factoring out the GCF.
The above expression can be simplified by factoring out -1.

Step-by-step explanation:
Your question isn't complete as you didn't give the sales tax percent. In order to solve the question, let's assume that the sales tax is 6%.
(a) What is the amount of sales tax that Mr. Speer has to pay?
This will be:
= Sales tax percent × Amount charged
= 6% × $300
= 6/100 × $300
= 0.06 × $300
= $18
The sale tax is $18
(b) What is the total amount Mr. Speer has to pay?.
The total amount will be the addition of the amount charged and the sales tax. This will be:
= $300 + $18
= $318

Answer:
B) x = +/- 17
Step-by-step explanation:
(4-x) /(3x+21)
The denominator cannot be zero
3x + 21 ≠ 0
3x ≠ -21
x ≠ -7
The domain of the function will be all real number except -7
{x | x ≠ -7}
