Lets just use
for an example. If the number is increased by 60% and the denominator is decreased by 20% we get the new fraction being:
. Since then new one is equal to 1, and the original is equal to
, we see that this manipulation of the fraction causes an increase of 100%.
Step-by-step explanation:
3(x + 1)(x + 7) − (2x + 5)²
3(x² + 8x + 7) − (4x² + 20x + 25)
3x² + 24x + 21 − 4x² − 20x − 25
-x² + 4x − 4
-(x² − 4x + 4)
-(x − 2)²
A squared number is never negative (provided x is a real number), so -(x − 2)² is never positive.

I just had this question on a test and the answer is 95.05
Answer: 36 months
