Answer 2

Use the image to answer the question.

An illustration shows two groups of tiles. The tiles are labeled, and the labels combine to form expressions below. The first set of tiles includes 2 stacked rectangular tiles, both labeled m, 2 stacked square tiles, both labeled plus 1, 4 stacked rectangular tiles, each labeled negative m, and 1 square tile labeled negative 1. The labels combine to form the expression 2 m plus 2 minus 4 m minus 1. The second set of tiles includes 2 stacked rectangular tiles, both labeled negative m, and 1 square tile labeled plus 1. The expression below this set of tiles reads left parenthesis question mark right parenthesis m plus 1.

What number will make the algebraic expressions represented by these models equivalent?
