Let x + 1.5 be length of segment above left hand
Let 2x be length of segment below left hand
15 = x + 1.5 + 2x
15 = 3x + 1.5
15 - 1.5 = 3x
13.5 = 3x
13.5/3= 3x/3
4.5 = x
x = 4.5
This is the length above the left hand.
2x must be then 4.5*2 = 9 foot
This is the length below the left hand.
Checking
4.5 + 9 + 1.5 = 15 foot
Adding length below left hand & length of left hand to right hand:
9 + 1.5 = 10.5
The right hand is hence 10.5 foot far up the pole.

Step-by-step explanation:
6x = 48
x = 8
Thinking about the graph of f(x), the rate of change is zero whenever there is an extremum.
First, differentiate f(x)

Next, find the zeros of f'(x) by factoring.

Now, we substitute these x-values into the
original equation to find the coordinates.
(-2.667, 11.481), (0, 2)
