Answer:
Option A
Step-by-step explanation:
We can try to factorize all the options one by one.
For A:
![x^{2} +5x-4\\=> x^{2}+4x+x-4\\=>x(x+4)+1(x-4)](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2B5x-4%5C%5C%3D%3E%20x%5E%7B2%7D%2B4x%2Bx-4%5C%5C%3D%3Ex%28x%2B4%29%2B1%28x-4%29)
We can see that the quadratic expression cannot be solved by factorization as the factors at the end of factorization are not equal in both brackets. So Option A is the correct answer for the given question.
Moreover we can also note that all the other quadratic expressions can be factorized ..

Step-by-step explanation:
Let the temperatures of Miami and Bangor be M and B degrees respectively.
According to the given information:
M = 3B + 22... (required equation)
Plug M = 82
82 = 3B + 22
82 - 22 = 3B
60 = 3B
B = 60/3
B = 20 degrees
Thus, the temperature in Bangor is 20 degrees.
