1) the answer to the radical is x^3+6x^2+12x+ 8
2) simplify this : x^3+6x^2+12x+ 8 + 3 = 27, into
3) this : x^3+6x^2+12x+ 11 = 27
4)Subtract 27 from both sides
x^3+6x^2+12x -16= 0
5) Use cubic formula.
x = 0.884499
Suppose you wanted to calculate the geometric mean of the numbers 2 and 32. This simple example can be done in your head. First, take the product; 2 times 32 is 64. Because there are only two numbers, the nth root is the square root, and the square root of 64 is 8.

1. You have that the speed is:
Where 
is the distance and 
is the time.
2. Tory pilots her boat 
before docking, therefore, his time is
3. Emilio continues for another 
, with a total of 
before docking. Therefore, his time is:
4. And his speed is:
5. Solve for 
and substitute the value into the formula of Tory's time:
The answer is:
