Answer:
Option B
Step-by-step explanation:
Given that the required reserve ratio is 20 percent.
Since banks are conservative they choose not to loan all their excess reserves
i.e. only 20% of deposits is kept as reserve and 80% lent.
This 80% will again be deposited in a bank and 80% of 80 i.e.64% would be lent. Thus this will form a geometric progression infinitely as
deposits 
with common ratio 0.8<1
Hence infinite sum = 
So deposit multiplier is B) equal to 5
Answer: I think the asnwer is c
Step-by-step explanation:
I suggest this because when your looking at the two different triangles your looking at the sides and the whole shape
I'm assuming this is x^2 + 3x - 4 and x(x^2 + 3x - 2)
1.) First distribute x(x^2 + 3x - 2) to get x^3 + 3x^2 - 2x.
2.) Because you are subtracting all the terms from x^3 + 3x^2 - 2x, it's the same thing as distributing -1 to x^2 + 3x - 4 and then adding it to x^3 + 3x^2 - 2x.
3.) -1(x^2 + 3x - 4) = -x^2 - 3x + 4
4.) Add (x^3 + 3x^2 - 2x) + (-x^2 - 3x + 4)
5.) x^3 + 2x^2 - 5x + 4 is your final answer.
