Answer:
Option A. -6.5
Step-by-step explanation:
we have
Solve for r
That means ---> isolate the variable r
Combine like terns left side of the equation
Divide by 0.5 both sides
The number of persons added to the population rises annually if the population's growth rate, r, is positive and stable.
Given statement,
If the growth rate r of a population is positive and remains constant, the number of people added to the population,
In the given case the solution will be the number of people added to the population " increases each year ".

Answer:
The values of x is 0 and 2.
Step-by-step explanation:
Given that the perimeter and area are the same so we can assume that x value remains the same in both equation. In order to find x, we can compare the equations and solve it :
A(y) = x² - 4x + 4
P(y) = -2x + 4
A(y) = P(y)
x² - 4x + 4 = -2x + 4
x² - 4x + 4 + 2x - 4 = 0
x² - 2x = 0
x(x - 2) = 0
x = 0
x - 2 = 0
x = 2
25/5 would be 5 as a whole number
