Problem 113 of 7
State the restrictions needed when rearranging A=1/2h(b1+b2) for h.
Using a hint is okay. It just tells the trainer to give you a little more review.

identify zero denominators and square-root domain limits.
Hidden until you reveal it.
Restriction set must include denominator and real-square-root restrictions created by the rearrangement.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Identify every division used or already present in the formula.
2. Mark quantities that cannot equal zero.
3. For square-root rearrangements, require the radicand to be nonnegative for real-valued answers.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Restrictions that confuse the target variable with the divisor created during rearrangement.
