Answer:

Step-by-step explanation:
The lowest point in New Orleans is 8 feet below sea level.
This can be represented numerically using 
(negative sign denotes below sea level)
The highest point in Chicago is 735 feet above sea level.
This can be represented numerically using 
(positive sign denotes above sea level)
It’s already in standard form
I am sure but I am going with Property if equation . this is say if x =2 then 2 x y = 2y .
The length of its diagonal in terms of r and s is √r² + s²
In order to get the length of the diagonal of a triangle, we will use the Pythagoras theorem:
Pythagoras theorem states that the sum of the square of the diagonal is equal to the sum of the square of the other two sides.
Given the following
Length = r feet
width = s feet
The diagonal "l" will be expressed as;
l² = r² + s²
Take the square root of both sides
√l² = √r² + s²
l = √r² + s²
Hence the length of its diagonal in terms of r and s is √r² + s²
