Add. (3t - 3) + (6t2 + 4t + 13) + (-8t2 + 11t - 1)? a) -2t2 + 18t + 9 b) -2t4 + 182 + 9 c) 2t4 - 18t - 9 d) 2t4 + 18t + 9

Let's simplify step-by-step.

3t−3+6t2+4t+13−8t2+11t−1

=3t+−3+6t2+4t+13+−8t2+11t+−1

Combine Like Terms:

=3t+−3+6t2+4t+13+−8t2+11t+−1

=(6t2+−8t2)+(3t+4t+11t)+(−3+13+−1)

=−2t2+18t+9
