Final answer:
To find the value of b from the equation 2b - hb = D³, you need to factor out b and then divide by (2 - h), resulting in b = D³ / (2 - h). The provided options are incorrect.
Step-by-step explanation:
The equation given is 2b - hb = D³. To solve for b, we need to isolate b on one side of the equation. Here's the step-by-step solution:
- Combine like terms by factoring out b from the left side of the equation: b(2 - h) = D³.
- Divide both sides of the equation by (2 - h) to solve for b: b = D³ / (2 - h).
So the correct answer is not directly listed in the options provided because each option has made a mathematical error or presents an incorrect form of the solution. The correct answer for b is b = D³ / (2 - h), which must be derived from correctly rearranging the original equation.
