Answer:
The answer would be 6.7b + 2
Step-by-step explanation:
In order to simplify this, simply add the like terms together.
3.8b + 2.9b = 6.7b
-7 + 9 = 2
Now just put those two together
6.7b + 2
Its given that

We need to find t when d = 74
Therefore,
or


t(16t + 37) - 2(16t + 37) = 0
(t - 2)(16t + 37) = 0
t - 2 = 0 or 16t + 37 = 0
t couldn't be negative.
Therefore, t = 2
Hence, it will take 2 seconds for the object to travel 74 feet.
