Answer: I don't think there would be any REAL solutions for x^2 + 16 <= 7.

Explanation: The expression is x^2 +16 <= 7 or x squared plus sixteen is less than or equal to 7. If we subtract 16 to 7, we get x^2 <= -9. You can't have any REAL solutions from square rooting -9. (You square root to make x^2 just x and do the same to the other side). If you're looking for an imaginary solution, then the answer would be 3i. Otherwise, no solution.
