Problema Solution
An aquarium holding African cichilds is 4 inches higher than it is wide. Its length is 27 inches, and its colume is 3780 cubic inches. What is the height and width of the aquarium.
Answer provided by our tutors
we interpret "colume" to mean "volume"
let 'x' represent its width in inches, then 'x+4' represents its height
3780 = x(x+4)27
solving for 'x' we have a positive value of x=10
10+4 = 14
the aquarium is 10 inches wide and 14 inches high
