(d) \( 5 x(2 x-3 y) \)

Did you know that the expression \( 5 x(2 x-3 y) \) can be expanded using the distributive property? By multiplying \( 5x \) with each term inside the parentheses, you’d get \( 10x^2 - 15xy \). This helps in simplifying or factoring polynomials later! Another exciting note is that this expression can be used in real-world scenarios like calculating the area of a rectangle where \( x \) and \( y \) represent dimensions. By applying algebraic expressions like this, you can efficiently model and solve problems involving areas, costs, or other practical applications in fields like engineering and economics!
