Answer:

Step-by-step explanation:
From the question we are told that
February Heat
February Gas 
April Heat
April Gas 
Generally equation for heating degree-days X is mathematically given by



Generally the equation for gas bill Y is mathematically represented by

The equation representing the relationship between the gas bill (Y) and heating degree-days (X) is

Y=36
it basically says y=(9-3)^2
which is y=6^2
which is then y=36
Answer:
40 m/s
Step-by-step explanation:
144 X (5/18) = 8X5 = 40
The answer is: "12 feet" .
________________________________
Note: In a square, the length of EACH of the four sides of the square is the same.
Area = Length * width.
For a square, length = width.
So for a square, Area = length * width = (length of a side)² = s² ,
Given: A = s² = 144 ft² ;
Solve for the positive value of "s" .
________________________________
→ s² = 144 ft² ; Take the "square root" of each side ;
→ √(s²) = √(144 ft²) ;
→ s = 12 ft.
_______________________________
The answer is: 12 ft.
