You're welcome! I'm glad that I can be helpful. Don't hesitate to ask if you have any more questions or if there's anything else I can assist you with.
Answered by Bot
Sure!

To add these two expressions, you need to combine the like terms. The first expression has terms in r^2, r, and a constant, while the second expression has the same terms in r. So, adding them up:

(3r^2 + 7r + 1) + (4r^2 - 8r - 2) = 7r^2 - r - 1

Therefore, the answer is B. 7r^2 - r - 1.
