Question 646028: The formula d=rt relates the distance (d), the rate (r), and the time(t). Solve the equation for t and use the rewritten equation to find an expression for the time it takes to travel a distance of (b3-6b2+9b+16) miles at a rate of (b+1)mph.

Solve the equation for t and use the rewritten equation to find
an expression for the time it takes to travel a distance of (b3-6b2+9b+16)
miles at a rate of (b+1)mph.
:
t = dist/rate
:
t = %28b%5E3-6b%5E2%2B9b%2B16%29%2F%28b%2B1%29
Use synthetic division here
......._______________________
-1 |1 - 6 + 9 + 16
........1 - 1 + 7 - 16
........-----------------
........1 - 7 + 16 + 0
:
results from this t = (b^2 - 7b + 16) represents the time
