Answer:
Step-by-step explanation:
Let C be the number of correct answers
Let B be the number of questions not answered
Let W be the wrong answers
Total = 2*C + B - W
It's a trinomial. There are three unrelated terms.

Answer:
- A) x > 3 and x < 2 has no solutions
Step-by-step explanation:
Given inequalities below and we are looking for a pair with no solution.
Let's verify:
A) x > 3 and x < 2,
- It has no solutions since the two inequalities have no common interval.
B) x > - 3 and x < - 2,
- Its solution is -3 < x < - 2, the interval between two given endpoints.
C) x > - 3 and x < 2,
- Similar to option B, the interval is between two endpoints:
D) x > - 3 and x > - 2,
- Its solution is x > - 2, the two inequalities cover almost same interval.
Step-by-step explanation:
Add 1 to both sides
Multiply both sides by 4
Take the square root of both sides
Subtract 5 from both sides
