|2x+1|=5If a and b are the solutions to the equation above, what is the value of |a-b|?
Correct answer: C. 5
- A. -5
- B. 1
- C. 5
- D. -1
Explanation
Now, to find the value of |a-b|, we can use the absolute value of the difference between a and b. In this case, a=2 and b=-3, so |a-b| = |2-(-3)| = |2+3| = 5. Therefore, the value of |a-b| is 5, as mentioned.
