Answer:
L = 7, W = 6
Step-by-step explanation:
All I did was I wrote out the equations, L = 2w - 5 and 2L + 2W = 26. I then substituted what L was into the equation and solves. Here's my work if you would like to see it.
One way you could solve this is to just multiply the top and bottom out so that you get 9/81, reducing it by 9/9 to get 1/9 or option C.
Another way would be to do
since dividing numbers with exponents would be subtracting the bottom exponent from the top exponent, provided that the base number (in this case 3) is the same for both. For this method, you would get 
, which is equal to 1/9 or .1 repeating, the same answer that you'd get with the first method.
