Answer:
Irrational. Thats the only one
Step-by-step explanation:
Answer:
Length = 5 feet
Breadth = (5/3) feet
Height(depth) = 2 feet
Volume of the entire tank = Length x Breadth x Height
=
----------(1)
Water is filled upto a height of (1/3) feet
Volume of water in the tank = Length x Breadth x Height
=
-------------(2)
Volume of space needed to be filled = (1) - (2)
= 
OR
Height of tank needed to be filled = 2 - (1/3) = (5/3) feet
Volume of space = Length x Breadth x Height of empty tank
= 
We could solve for x, but notice that the same expression is being squared in both (x+1)
if (x+1)^2 - 3 = 22 then
(x+1)^2 = 25
that would mean that (x+1)^2 - 5 = 25 - 5 = 20
