Answer: 2048 ft
Step-by-step explanation:
Given
The length of each sidewalk is 
There are eight sections of the sidewalk
The total length of the sidewalk is 

Total length of the entire sidewalk is 2048 ft
If we were to view the ramp from its side, the profile would resemble a right triangle with a 90 degree angle where the sofa meets the floor.
In this case, the two legs of the right triangle are 55 inches and 28 inches, and we looking for the length of the hypotenuse.
We can use Pythagorean Theorem which states:

where a and b are the legs, and c is the hypotenuse.




c = 61.717 inches
To the nearest tenth, the answer is 61.7 inches.
Answer:
Step-by-step explanation:
x^2 - 17x - 60
(x - 20)(x + 3)
x^2 + 3x - 20x - 60
x^2 - 17x - 60
(x + 20) is not one of the factors
using F.O.I.L., it would have been
x^2 + 17x - 60
It would be B. because the rise over run is 31.25 over 5 which is divided to 6.25 which is rounded to 6.3
