Answer:
A =256 cm^2
Step-by-step explanation:
The perimeter of a square is 64 cm
P = 4s where s is the side length
64 = 4s
Divide by 4
64/4 = 4s/4
16 =s
The side length is 16 cm
The area of a square is
A = s^2
A = 16^2
A =256 cm^2
Answer:

Step-by-step explanation:





Answer:
y = 40x + 35
Step-by-step explanation:
Let x represent each month of service in the equation
Since it is $40 for each month, the price for each month can be represented by 40x.
The $35 fee will represent the y intercept, and will be added to 40x in the equation.
Put this together in the equation y = mx + b
y = 40x + 35
So, the linear equation to model the situation is y = 40x + 35
