Final answer:
The equation to solve for 'h' in A = n(b1 + b2)h is h = A / n(b1 + b2). The options provided are incorrect due to a typo and not reflecting the proper algebraic manipulation.
Step-by-step explanation:
The original equation is A = n(b1 + b2)h, and we need to solve for h. First, we divide both sides of the equation by n(b1 + b2) to isolate h on one side:
h = A / n(b1 + b2)
Note that there is no 'Oh' in the correct algebraic manipulation; it's likely 'Oh' is a typo for 'h'. Hence, none of the given options are correct, as they include 'Oh' instead of 'h' and do not represent the correct algebraic steps needed to isolate 'h'.
