The perimeter of a beach volleyball court is 54 m. The difference between its length and its width is 9 m.
a) Create a linear system to model this situation.
b) Solve the system to determine the dimensions of the court.

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)

What is the missing step in this proof ?
