4 feet 6 inches
Step-by-step explanation:
P=2(l+w) [the addition of all sides of the rectangle] 
P = 40'
L = 15’6”
So, 40' = 2 (15’6’ + w)
40' = 31’ + 2w
9' = 2w
4’6” = w
If it's easier you can break it change feet into inches and then change back to feet.
        
             
        
        
        
since u know that there is 60 minutes in a hour do 60 times 3 and u will get 180.then do 180 divided by28 and u will get ur final answer which is 6 minutes and 12 seconds

Answer:
Step-by-step explanation:
The - tells you that it is upside down. So that much of your choice is correct for certain.
The 1/8 squishes the graph something fierce. So of those graphs given, the one you chose is most likely correct. But you are right to be a little miffed at the question. You should never have to choose an answer with only a picture to guide you. If you have a graphing calculator, try y = -1/8 x^2 which is a good candidate for all the graphs.
