The expressions provided can be analyzed as follows:
1. **4x + 3x** simplifies to **7x**.
2. **(4 + 3)x** also simplifies to **7x**.
3. **7x** is already in a simplified form.
Now let's look at **7x²**. This expression is different from the others because it has x squared instead of just x.
Thus, the expression that is not equivalent to the others is **7x²**.
