It looks like you've written $(x + 4)$, but it's incomplete—are you trying to solve for $x$, simplify an expression, or expand something?

Let me know what you'd like to do with $(x + 4)$, and I'll be happy to help!

Here are some related questions for you:

1. What happens when you square $(x + 4)$?
2. How would you expand $(x + 4)(x - 2)$?
3. What is the value of $x$ if $(x + 4) = 0$?
4. How would you solve $3(x + 4) = 18$?
5. How do you factor expressions like $x^2 + 8x + 16$?

Tip: When working with binomials like $(x + 4)$, always be clear if you're adding, subtracting, or multiplying them with other terms!
