Answer:
6
Step-by-step explanation:
W=L-2
A=L*W
48=L(L-2)
48=L^2-2L
You factor and then you get L=8
W=8-2=6

Answer:
X=-Y
Step-by-step explanation:
...........................
For the first flower she has a choice of 15. For the second 14 (15 minus the one that was already used). For the third 13, and so on.
Each of the first 15 can be match with any of the second 14. Any of the first pairs can be matched with ant of the third 13 and so on.
This gives us
Number of Selections = Choices for Flower 1 x Choices for Flower 2 x Choices for Flower 3 x Choices for Flower 4 x Choices for Flower 5



You could also calculate this as the permutation 
If the circumference is 34 Times PI that means that 34 is the diameter.
So that means that you can just divide the diameter by 2 to get the radius (Because the radius is half of the diameter.)
So the answer is the diameter is 34 and the radius is 17
