When analyzing AE, it is important to know the factors that determine C, Ip, G and NX because those factors A. influence the level of AE and help us understand the GDP in the economy. B. show us how macroeconomic equilibrium is determined in the AE model. C. helps us understand how AE and real GDP are related. D. All of the above.

D. All of the above.

Explanation:

In the Aggregate Expenditure model or approach to GDP, GDP is calculated using the following formula:

GDP = C + I + G + NX (X-M)

Where:

As can be seen, each of the elements of the equation are necessary to understand (calculate) GDP by the AE approach. Each element is also important to show how macroeconomic equilibrium is reached. Thus, the correct answer is D.

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
