Answer:
6h = 36ft + 3h
The height h of each floor is 12ft
Step-by-step explanation:
From the question,
The two buildings have the same total height.
Let the total height of each building be H, that is
H (for one building) = H (for the other building)
Also,
For one building, there are 6 floors each with height h, that is
H = 6h
For the other building, there is a ground floor of 36 ft and 3 other floors each with height h, that is
H = 36ft + 3h
To find the height h of each floors,
Since the two buildings have the same total height, we can write that
H (for one building) = H (for the other building),
Then,
6h = 36ft + 3h
This is an equation that could be used to find height h.
To solve for h,
6h = 36ft + 3h
Then,
6h - 3h = 36ft
3h = 36ft
h = 36ft / 3
h = 12ft
Hence, the height h of each floor is 12ft

The quadratic formula is the result of completing the square for ax^2+bx+c=0 when a,b, and c are unknown values. This result is:
x=(-b±√(b^2-4ac))/(2a), we have x^2-x-2=0 so
x=(1±√(1+8))/2
x=(1±√9)/2
x=(1±3)/2
x=-1 and 2
