Answer:
h = 17.65 m
Step-by-step explanation:
The given equation gives the speed at impact :

h is height form where the object is dropped
Put v = 18.6 m/s in the above equation.

So, the object must be dropped from a height of 17.65 m.
The answer is 3n+1
What i did was add the like terms.
-7n+10n= 3n
-7 + 8=1 (the 7 is negative because it's being subtracted)
if you put it together you get 3n+1
hope this helps
