It's not clear whether you meant 30n^(2b) or [30n^2] b.
I will assume the latter.
b can then be factored out of all three terms, resulting in
b [30n^2 - 87n + 30] = b [ 3 ] [10n^2 - 29n + 10 ]
Can you factor this further?
We have been given that the profit that the vendor makes per day by selling x pretzels is given by the function 
. We are asked to find the number of pretzels that must be sold to maximize profit.
First of all, we will find the derivative of our given function.
Now, we will find the critical point by equating derivative with 0 as:
Therefore, the company must sell 300 pretzels to maximize profit and option B is the correct choice.
7 x 2 = 14
3 x 1 = 3
14+3 = 17
answer 17 unit^2
Is their a picture that you’re referring to ?
If you’re asking how much do you need to make right angles it should be 90 degrees
Concept: Basically there are three relations in function relation
a) Reflexive Relation (aRa),
b) Symmetric Relation aRb ⇒bRa ,and
c) Transitive Relation aRb and bRc ⇒cRa
Here, all alphabets are in their usual meanings
(i) Reflexive Relation: A relation R is said to be reflexive on X if (x,x) belongs to R such that every x belongs to set X.
In the given question the statement is RS = RS
It means RS element has its own image as RS
Hence, the statement RS = RS will be reflexive.
Therefore, the correct option will be B)reflexive.
