a) expand the dog house to a larger size so it can hold more heat.
b) heat dog houses with electric blankets and space-heaters.
c) insulate dog houses and put straw inside.
d) allow the dog to sleep on the floor in the garage.

The most practical protection you can do to your dog is: C. Insulate dog houses and put straw inside.

Insulation is the easiest and fastest way among the choices that would really help to keep your dog warm inspite that he lives outside your home.  

But if you really want to ensure for the safety of your dog, you let him sleep inside your home until the cold season is over. Dogs are family and they should be kept safe.

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

hope this
