To determine how much will it take to clean a 120ft driveway considering that it took him 2hs to clear 10ft and that the cleaning rate is constant, you can use cross multiplication:
10ft______2hs
120ft_____xhs
If the cleaning rate is the same, then the ratios between both are the same:
From this expression, you can determine the time by multiplying both sides of the equal sign by 120
It will take him 24 hours to clear the 120ft driveway.

Answer:
The given function 
was replaced with 
then the value of k is -3
that is k=-3.
Step-by-step explanation:
The given function is 
and when x=x+k then 
Now to find the value of k:
Put x=x+k in the function f(x)
Now comparing equations (2) and (3) we get
Therefore k=-3
Therefore the given function was replaced with then the value of k is -3
that is k=-3.
A= 1/2 bh
2A/b=h
just solve the original formula in terms of the height
