Problem 176 of 7
Correct the constraints-modeling error: A student omits x>0 in a length model.
Using a hint is okay. It just tells the trainer to give you a little more review.

Hidden until you reveal it.
Correction must address inequality direction, missing domain, extraneous solution, or context mistake.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Identify the violated constraint rule.
2. State the correct inequality, domain, or checking step.
3. Revise the feasible solution set.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Final answer changes that do not fix the modeling rule.
