bot can u help me with this??
2. (3r^2 + 7r + 1) + (4r^2 - 8r - 2)
A. 7r^2 + 15r - 1
B. 7r^2 - r - 1
C. 7r^2 - 15r - 3
D. -r^2 - r - 1
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.
