1. The problem asks for help with part d of question 2. Since the exact question is not provided, I will explain how to approach a typical part d in algebra or math problems, often involving solving or simplifying expressions. 2. Generally, part d might require solving an equation, simplifying an expression, or applying a formula. The key is to identify what is asked and use the appropriate method. 3. For example, if part d asks to solve for $x$ in an equation like $ax + b = c$, use the formula: $$x = \frac{c - b}{a}$$ 4. Important rules: - Always perform the same operation on both sides of the equation. - Simplify expressions step-by-step. - Cancel common factors carefully, showing intermediate steps with \cancel{}. 5. Without the exact question, I recommend reviewing the problem statement, identifying knowns and unknowns, and applying algebraic manipulation accordingly. If you provide the exact text of question 2 part d, I can give a detailed step-by-step solution.
