let
x--------> the monthly fee
y--------> the administration fee
we know that
--------> equation 
--------> equation 
Multiply by
equation 
------> equation 
Adds equation
and equation 

Find the value of y

therefore
the answer is
the administration fee is equal to 
Step-by-step explanation:
I think it is hilo hawii 480 cm it has the longest cm
Will's test had more questions
y = Acos(Bx) + D;
D = 4, A = 2. Now T = 2π/B = 5π/8, B = 2π/(5π/8) = 16/5
WE get y = 2cos(16/5x) + 4
Answer:
C. x²+12x+36
Step-by-step explanation:
Since a square's area is figures out with
and since the length is x+6, then we get:
(x+6)²=
(x+6)(x+6)=
<em>Use </em><em>FOIL</em><em> method.</em>
First: x²
Outer: 36
Inner: 6x
Last: 6x
x²+36+6x+6x=
x²+12x+36
The answer that fits is C. x²+12x+36.
