AlexFokin [52]
This means 35% used buses. 3+4=7, so 20% took school buses while 15% took public buses. 65%-35%=30% who mean the difference, so 30% is 360. You ask what is 15% -- that's half of that difference, or 180.

Answer:

When x

Step-by-step explanation:

When x is smaller than 2, the resulting value under the square root will become negative. Since it is impossible to take the root of a negative number, the expression is thus undefined, however, it can be represented with the imaginary number i where i = \sqrt{-1}.

Hope this helps :)
