Rayon needed to find the perimeter of an equilateral triangle whose sides measure x + 4 cm each. Jake realized that he could multiply 3 (x + 4) = 3x + 12 to find the total perimeter in terms of x. Which property did he use tomultiply?

Rayon used the following mathematical statement to show he could change an expression and still get the same answer on both sides:10 × (6 × 5) = (10 × 6) × 5Which mathematical property did Rayon use?
