Answer:
10 19/10 meters
Step-by-step explanation:
Step one:
given data
let the amount of string used for the soccer field be x
and the amount used for coach spot be y
Also, let the total string used be represented as T
Step two:
Hence the expression for the total is
T= x+y
T= 9 1/2+ 2 2/5
T= 9.5+ 2.4
T= 11.9
or 
T= 119/10 meters 
or
T= 10 19/10 meters

Answer:
The picture where the red image is the skinniest
Step-by-step explanation:
The graph P(x) denotes the graph of the parent graph for all the functions. And, It includes the vertex of (0,0) and points which are shown below:
x      f(x)
-2      2
-1       1
0       0
1         1
2       2
Now as we can see in the attached figure i.e it changed the function points i.e given below for l(x) = 12P(x)
x      f(x)
-2      24
-1        12  
0        0
1        12
2       24
This depicts that it has a skinner graph that includes redish graph
