What is the perimeter of the triangle expressed as a polynomial?
Length: 8x-2
Length: 5x-4
Width: 9x-3
If you could show me how you got the complete answer I would really appreciate it.
The perimeter is the sum of the lengths of the three sides of the triangle. If "width" is the length of the 3rd side, then the perimeter is P = (8x-2) + (5x-4) + (9x-3) P = 8x + 5x + 9x -2 -4 -3 P = (8+5+9)x -(2+4+3) P = 22x - 9
