Will ran the longest
He ran for 56.57 yards, 13.56 yards longer than James.
Step-by-step explanation:
Step 1 :
Will ran the diagonal across a square field measuring 40 yards in each side.
The diagonal of a square can be obtained by the square root of the sum of the squares of its 2 sides [Because it forms the hypotenuse of a right angle triangle]
Hence when the side is 40 yards , the diagonal would be

So Will ran for 56.57 yards
Step 2 :
James ran the diagonal of a rectangular field with 25 yards length and 35 yards width.
The diagonal of the rectangle can be obtained by the square root of the sum of squares of its length and width.
Hence when the length is 25 yards and width is 35 , the diagonal would be
yards
So James ran for 43.01 yards
Step 3 :
Will ran for 56.57 yards and 43.01 yards.
Hence Will ran for longer distance of 56.57 yards, which is 13.56 yards more than James.
The formula of find the slope is -0.4285
use y2 - y1 over x2-x1
To combine these terms you would add up the a's and b's.
4a+b+a is the same as 4a+a+b. Anything without a constant in front has a value of 1. You have 4a's and you need to add another a. That equals 5a's. The b is left alone since you can only add like variables.
The answer would be C) 5a +b
