show me a calculation! it would be better if u can edit on my picture below and write the answer but anything is fine. please take your time!

Answer:
3.12 meters
Step-by-step explanation:
You already know that the answer is 9.36/3. Since all of the digits in the dividend are divisible by 3, you can easily do this division in your head (mental arithmetic). The first attachment shows it done using the usual long-division format.
The second attachment shows a calculator result--which is what most of us might use if we don't want to do the mental arithmetic.
We're never quite sure what "show your calculation" is supposed to mean when the result is computed without writing anything down.

2 ways: Easy and hard
Hard=A
Easy=B
A: 1/2x+4 work from there so we do fun stuff with it make something that can be simplified so 1/2x+4 times (2/2)=x+8 now square the whole thing and put the result in a square root thingie (x+8)^2=x^2+16x+64
multiply the whole thing by 4/4 and put ![\sqrt{16} [\tex] on top so then [tex] \sqrt{x^2+16x+64}](https://tex.z-dn.net/?f=%20%5Csqrt%7B16%7D%20%5B%5Ctex%5D%20on%20top%20so%20then%20%0A%5Btex%5D%20%5Csqrt%7Bx%5E2%2B16x%2B64%7D%20)
times

=
to solve it, factor out the 16 in the square root and then square root 16 to get 4
then it will be (4 times square root of equation)/4=square root of equatio
factor square root of equation and square root it and get x+8
divide by 2 to get 1/2x+4
B: 1/2x+4
put stuff that cancels out
1/2x+3x-3x+4+56-56
move them around
3 and 1/2x-3x+60-56
or
2x-3x+1 and 1/2x+30-20+30-36
then just add like terms to solve
