Answer:

6x^2 + 8x + 28

Step-by-step explanation:

2 times the length plus 2 times the width gives the perimeter

2(3x^2 + 3x + 6) + 2(x + 8)

6x^2 + 6x + 12 + 2x + 16

6x^2 + 8x + 28

If the graph is linear, it would be a line, for example:
y = 2x - 5

If the graph is quadratic, it would be a curve, for example:
y = x^2 - 5x + 6
