Hello from MrBillDoesMath!
Answer:
The second choice
Discussion:
The first choice is not a polynomial because it contains sqrt(x)
The third choice is not a polynomial because it contains (1/x)
The fourth choice is not a polynomial because it contains x in the exponent (ie. 5^x)
Thank you,
MrB

Isiah is 5.83 miles away from his starting point.
When you draw the the miles Isaiah walks, you will discover that you are forming a right angle triangle.
To measure the length from the starting point to the ending point. We must used the Pythagorean equation. Where in the square of the hypotenuse is equal to the sum of squares of the other two sides.
a² + b² = c²
a = 3 miles 3² + 5² = c²
b = 5 miles 9 + 25 = c²
c = hypotenuse. 34 = c²
We must get the hypotenuse, since 34 is the square of the hypotenuse we must look for its square root.
c² = 34
c = √34
c = 5.83 miles
