Explanation:

Expansion can be referred to as the stage of a business cycle where there is a growth in GDP for most of the year. it can be both in 2nd and 3rd quarters of the year, moving from a rough patch to its peak or growth

when a country is out of recession for example, as the GDP rises and gets to it's peak, what follows after that is  availability of employment, Market equity, and boost the consumer's ability and self confidence.

Expansion can be called the recovery of an economy were money becomes available to borrow., business of consumers can rise again Growth per capital grows, and the market performs well.

Expansion can only arise ones a phase of business cycle declines

happiness is the correct luck

explanation:

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
