let X equal the length along the river
so 50-X is the distance away from the river
A = 50 X - X^2
One hundred meters of fencing is available to enclose a rectangular area next to river give a function
A that can represent the area that can be enclosed, in terms of X?

Because the river is there, only 3 sides need to be fenced.
A = x ( 100 - 2 x ) =
100 x - 2 x ^ 2 =
2 ( 50 x - x ^ 2 )
A = x ( 100 - 2 x ) =
100 x - 2 x ^ 2 =
2 ( 50 x - x ^ 2 )
what if
A= ________x^2 + ______x
what should I insert?
A= ________x^2 + ______x
what should I insert?
A(x)= 50x - x²/ 2
f(a)= x+2y=100
f(a)=50x-0.5x²
f(a)=50x-0.5x²
Why you use 2y,can you please clarify??
lenght = x
width = y
width = y
120 meters fencing is available to enclose a rectangular area next to river the function a that can represent the area that can be enclose in terms of x.
