Answer:
D) 160
Step-by-step explanation:
20% × n = 32
20
/100
× n = 32
Multiplying both sides by 100 and dividing both sides by 20,
n = 32 × 100
/20
n = 160
ANSWER
None of the above
EXPLANATION
The quadratic expression given to us is
![6 {x}^{2} + 2x - 21](https://tex.z-dn.net/?f=6%20%7Bx%7D%5E%7B2%7D%20%20%2B%202x%20-%2021)
If the discriminant of this quadratic expression is a perfect square, then it has rational factors,
If we compare the above expression to the general quadratic expression,
![a {x}^{2} + bx + c](https://tex.z-dn.net/?f=a%20%7Bx%7D%5E%7B2%7D%20%20%2B%20bx%20%2B%20c)
We have,
![a=6,b=2,c=-21](https://tex.z-dn.net/?f=a%3D6%2Cb%3D2%2Cc%3D-21)
The discriminant is given by,
![D = {b}^{2} - 4ac](https://tex.z-dn.net/?f=%20D%20%3D%20%20%20%7Bb%7D%5E%7B2%7D%20%20-%204ac)
Thus
![D = {2}^{2} - 4(6)( - 21)](https://tex.z-dn.net/?f=%20D%20%3D%20%20%20%7B2%7D%5E%7B2%7D%20%20-%204%286%29%28%20-%2021%29)
![D = 4 + 504 = 508](https://tex.z-dn.net/?f=%20D%20%3D%20%20%204%20%20%2B%20504%20%3D%20508)
Since 508 is not a perfect square, the expression
![6 {x}^{2} + 2x - 21](https://tex.z-dn.net/?f=6%20%7Bx%7D%5E%7B2%7D%20%20%2B%202x%20-%2021)
has no rational factors.
Therefore D is the correct answer.
