Answer:
9in Squared
Step-by-step explanation:
a square is 4 equal length sides, 12 / 4 = 3, then multiply two sides of the square, 3 x 3 = 9.
Answer:
the difference is number 4
Answer:
The answer is 4 liters.
Step-by-step explanation:
We want a final 25% solution, which means that the solvent should constitute 25 percent of all the liters of solution.
Let us call 
the litres of 40% solution, so when they are added to the 12 litres of 20% solution, the total litres of the new solution are:
of these liters, 25% must be the solvent:
Now for the 40% solution, the liters of the solvent are 
, and for the 20% liter solution, the liters of solve are 
liters. Thus the total liters 
of the solvent are
Therefore
