= 3x^2 - 7x - 4 - 6x^2 + 6x - 1 (distribute negative sign)
= -3x^2 -x - 5 (combine like terms)
(3x^2-7x-4)-(6x^2-6x+1)

Write the perimeter of the figure as a polynomial. Simplify. A trapezoid is shown. The top side is labeled 2 x. The right side is labeled 4 x plus 1. The bottom side is labeled 3 x. The left side is labeled 4 x plus 1.
The perimeter of the trapezoid is the sum of all four sides.
2x + (4x + 1) + 3x + (4x + 1)
= 13x + 2
Thus, the polynomial representing the perimeter of the trapezoid is 13x + 2.
2x + (4x + 1) + 3x + (4x + 1)
= 13x + 2
Thus, the polynomial representing the perimeter of the trapezoid is 13x + 2.
