Garcia is modeling the equation 5 x (negative 1) = negative 2 x 6 by using the following tiles: 5 positive x-tiles and 1 positive unit tile to represent 5x (– 1) 2 negative x-tiles and 6 positive unit tiles to represent –2x 6 Which statement explains Garcia’s error? Garcia should have used 5 positive x-tiles and 1 negative unit tile to represent 5x (–1). Garcia should have used 2 positive x-tiles and 6 positive unit tiles to represent –2x 6. Garcia should have used 1 negative x-tile and 5 positive unit tiles to represent 5x (–1), and he should have used 6 positive x-tiles and 2 negative unit tiles to represent –2x 6. Garcia should have used 5 negative x-tiles and 1 positive unit tile to represent 5x (–1), and he should have used 2 positive x-tiles and 6 negative unit tiles to represent –2x 6.
