The diagram shows a large square divided into squares of three different sizes. What percentage of the large square is shaded?

Create and solve a linear equation that represents the model, where squares and triangles are shown evenly balanced on a balance beam. assume the weight of a square is 1 unit and the weight of a triangle is unknown.

If f(x)=2x-6 and g(x)=3x+9, find (f-g)(x)

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