2n + 2n = 2n squared and 17 + 21 = would be 38
so answer is : 38 + 2n squared

Answer:
1.73 miles per runner
Step-by-step explanation:
8.65/5 = 1.73
Answer: 11.0 or 11
Step-by-step explanation:
To find the distance first find the difference between the coordinates. find the change in the x and y coordinates and square them to add them to get a number and find the square root of that same number to find the distance.
x coordinates: 5-(-6)= 11
y coordinate: 7-6 = -1
Now square them
11^2 + 1^2 = l^2 where l is the distance
121 + 1 = l^2
122 =l^2
l =
l = 11.045 Rounded to the nearest tenth is 11.0
