Answer:
The answer is
N(a) = (a + 25) /4
Step-by-step explanation:
If the function is
A(n) = 4n -25
and we wish to get the inverse function N(a)
We let
A(n) = a
n = N(a)
Plugging in the values
a = 4 N(a) - 25
Arranging the equation:
4 N(a) = a + 25
N(a) = (a + 25) /4
Answer:
20 cm
Step-by-step explanation:
First, find the length of one side of the square. Here A = 25 cm^2 = s^2, where s represents that length. Thus, s = 5 cm.
Next, find the perimeter of the square. P = 2(length) + 2(width). For a square, where length=width, P = 4s.
In this problem, P = 4(5 cm) = 20 cm
The answer is 23/42. CD is 42
