A rectangular garden has a walkway around it. The area of the garden is 4(2.5x +3.5). The combined area of the garden and the walkway is 4.5(4x + 5). Find the area of the walkway around the garden as the sum of two terms.

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

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)
