Answer:
P = -4
Step-by-step explanation:
Assuming that x = 20 and y = 24, you have to plug in these numbers for x and y to get to this equation P = 20 - 24. You should get -4 when you subtract 24 from 20 giving you a negative answer.

Answer:
10.25%.
Step-by-step explanation:
The increase of the lengths and width is by a factor 1.05. ( as the increase is 5%).
So the increase of the area is by a factor 1.05^2 = 1.1025.
So the percent increase in the area = 1.1025 - 1
= 0.1025
= 10.25%.

Answer:
decay; 8% decrease per time period
Step-by-step explanation:
The growth factor is the base of the exponential term. The growth rate is 1 less.
growth rate = 0.92 -1 = -0.08 = -8%
When the growth rate is negative, it is exponential decay withe the amount of decrease equal to the magnitude of the rate.
A growth rate of -8% represents exponential decay, with a decrease of 8% per time period.
