Which polynomial is modeled by the following set of algebra tiles?
The image shows 3 big unshaded square tiles, 4 unshaded rectangular tiles, and 6 small shaded square tiles.
Each of the 3 big unshaded square tiles is labeled x squared at its center. Each of the 4 unshaded rectangular tiles is labeled x at its center. Each of the 6 small shaded square tiles is labeled 1 at its center.
Each vertical side of the unshaded rectangular tiles has the same length as a side of a big unshaded square tile. Each side of the small shaded square tiles has the same length as a horizontal side of a unshaded rectangular tile.
