Suppose a firm in a competitive market increases its output by 20 percent. As a result, the price of its output is likely to A. decline by 20 percent. B. remain unchanged. C. increase by less than 20 percent. D. decline by more than 20 percent.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

here's one link :

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

answer; the correct answer should be (demonstrations); good luck
