Question

1. explain what the second expression, 12x-612x - 612x-6, indicates about finding the perimeter of the rectangle.

Explanation:

Assuming there was a first expression (maybe combining like terms or a different form), the expression \(12x - 6\) (correcting the repeated typo) for a rectangle's perimeter implies a simplified form. A rectangle's perimeter is \(P = 2(l + w)\). If length and width expressions were combined (e.g., if length and width had terms with \(x\) and constants, combining like terms led to \(12x - 6\)), this expression shows the perimeter after simplifying the sum of all sides (2 lengths + 2 widths) by combining like - term coefficients (for the \(x\) - terms) and constant terms, resulting in a linear expression representing the total distance around the rectangle.

Answer:

The expression \(12x - 6\) (after correcting the typo) represents the perimeter of the rectangle in a simplified form, obtained by combining like terms from the sum of the lengths of all four sides (2 lengths and 2 widths) of the rectangle.
