Answer :
To represent \( x - 2 \) using algebra tiles, we need to consider two types of tiles:
1. Tiles representing \( x \).
2. Tiles representing the constant terms, where positive units are shown by a positive tile (e.g., +1) and negative units by a negative tile (e.g., -1).
Here's how we can break down \( x - 2 \):
1. The term \( x \) is represented by one \( x \)-tile.
2. The term \(-2\) is represented by two negative unit tiles (each representing -1).
Combining these, we have the following representation:
- One \( x \)-tile for the \( x \) term.
- Two negative unit tiles for the \(-2\) term.
Therefore, the correct representation of \( x - 2 \) using algebra tiles is:
- One \( x \)-tile.
- Two negative unit tiles.
