Y=-12x+6. I used the slope intercept form y=mx+b to solve.
Subtract 180 - 34 = 146
You know ∠BPD adds up to 146°
Since 
bisects ∠BPD, you know that ∠BPC and ∠CPD are equal to each other.
Divide 146 by 2 = 73
m∠CPD = 73°

Let x represent the time spent for valleyball
Then swimming will be 2x
x + 2x = 4.5
3x = 4.5
x = 4.5/3
x = 1.5
Time spent on valleyball: 1 1/2 hours
Time spent on swimming: 3 hours
3/4
3.0/4=0.7R0.2 or 0.7 + 0.2/4
0.20/4=0.05R0.00 or 0.05 + 0.00/4
now put it all together
0.7R2 = 0.7 + 0.05R0.00 = 0.75 + 0.00 = 0.75
Length = 11
Width = 9
Area we need = 126
So Area = length * width
126 = 11 * 9
Now.. this is obviously wrong.. they want us to find the correct length..
126 = L * 9
126/9 = L
L = 14
Now since they ask about how much farther you need to extend, take the final and subtract from the original
14 - 11 = 3
Answer is 3.
