I don’t have to have ads. When I wasn’t signed up I had to but I logged in and now I don’t have to watch ads.
The numerator factors as (t-8)(t+4), so the whole thing is (t-8)(t+4)/(t-8). Now we can cancel the t-8 AS LONG as t isn't equal to 8, otherwise, we are canceling a zero from both numerator and denominator which is invalid. What is left is t+4.
So your choice was right.
We can't see the graph so we don't know the question

Step-by-step explanation:
Answer:
Distance is greater than the displacement.
Step-by-step explanation:
We are given that a train on a straight track goes in the positive direction.
We have to find that distance covered by the train is greater than, lees than or equal to its displacement.
Train covered distance in positive direction=6.7 km
Train covered distance in back=4.0 km
Distance covered by the train=6.7+4=10.7 Km
Because distance is the length of path covered by object.
Displacement =Final position -Initial position
Displacement =6.7-4=2.7 km
10.7 > 2.7
Distance > Displacement
Hence, Distance is greater than the displacement.
