Answer:
y = 4000/x²
Step-by-step explanation:
The volume of the building is expressed as;
V = x²y where;
x is the length and width of the base.
y is the height of the building
Given
Volume V = 4000m³
Substitute the given volume into the equation as shown;
4000 = x²y
Make y the subject of the formula by dividing both sides by x²
4000/x² = x²y/x²
4000/x² = y
Rearrange
y = 4000/x²
Hence equation for y, the height of the building, in terms of x, the length and width of the base is expressed as y = 4000/x²

or, 12x+15=75
or, 12x=75-15
or, 12x=60
or, x=60÷12
or, x=5

or, 6y-27=105
or, 6y=105+27
or, 6y=132
or, y=132÷6
or, y=22
