A corner shelf is in the shape of a triangle. One side measures [tex]2x^2 + 2x -1[/tex] while another side measures [tex]5x + x^2 - 3[/tex]
What is the total of two sides? Show all work.
If the perimeter measures[tex]3x^3 - x^2 - 8x +1[/tex] what is the length of the missing side? Show all work.
If we know that [tex]x =2[/tex] then what are the lengths of the three sides of the triangle? Show all work.
Is it possible to have these side lengths? Why or why not?
