Simplify this expression: 5a + 11b + 12b + 13a

3. is it possible to solve x (t ) for t, substitute it into y(t) to eliminate the parameter, t, and write it as a rectangular equation with x and y instead? why or why not? these are the equations i am working with: •x (t)=0.0411905(t^2)+(-0.164619)t+28. 0114 and • y (t)=-0.024127(t^2)+(-0.591143)t+(-8 7.4403)
