Now I am not sure what length you're supposed to find for problem 9, but x = 3.3 i think.
10.)
(14+x)+(x+21) = 13
2x+35=13
2x = -22
x = -11
FE = -11 + 14 = 3 units
11.)
10 + 2x - 10 = 3x - 8
2x = 3x - 8
-x = -8
x = 8
10 + 2(8) -10 = 16 units
The answer is 17, because 41 minus 24 is 17.

Answer:
f(1) = 12
Step-by-step explanation:
We know that f(x)=f(x-1)+2x+1
We are told that f(2) = 17
Use the first equation to calculate f(1). Since f(2) is known and f(x-1) will become f(1) after f(2-1) is simplified to f(1).
17 = f(2-1)+2*2+1
f(2-1) = 17 - 5
f(1) = 12
To find the inverse of any function, switch the x's with y's and vice versa.
The current equation given is 
Switch the 
with 
and switch the with
After doing so, we'll have the following equation:
Now, let's move the variables around so that y is isolated on the left side again.
Subtract both sides by 4y
Subtract both sides by x
Divide both sides by -4
That is the answer.
Have an awesome day!
