The function of the length z in meters of the side parallel to the wall is A(z) = z/2(210 - z)
<h3>How to write a function of the length z in meters of the side parallel to the wall?</h3>
The given parameters are:
Perimeter = 210 meters
Let the length parallel to the wall be represented as z and the width be x
So, the perimeter of the fence is
P = 2x + z
This gives
210 = 2x + z
Make x the subject
x = 1/2(210 - z)
The area of the wall is calculated as
A = xz
So, we have
A = 1/2(210 - z) * z
This gives
A = z/2(210 - z)
Rewrite as
A(z) = z/2(210 - z)
Hence, the function of the length z in meters of the side parallel to the wall is A(z) = z/2(210 - z)

umm ,this is too long could you maybe putt it in smaller form so I can answer
Answer:
59.9 mph or rounded to the nearest tenth (60 mph)
Step-by-step explanation:
Speed=Distance÷time
Distance-1798
Time-30
Speed-?
1798÷30=59.9mph or 60mph
Answer:
x²+x-30
x=5
Step-by-step explanation:
The equation is
(x+3+x-1)/2 × x=30
x²+x-30 (it's the quadratic equation)
x²+6x-5x-30=0
x(x+6)-5(x+6)=0
(x+6)(x-5)=0
x=-6
x=5
It's impossible for Length to be negative
So x=5
