The lengths of two sides of a triangle are shown below: Side 1: 3x2 − 6x − 10

Side 2: 9x + 5x2 − 8

The perimeter of the triangle is 6x3 + 10x2 − x − 3.

Part A: What is the total length of the two sides, 1 and 2, of the triangle? (5 points)

Part B: What is the length of the third side of the triangle? Hint: Take Perimeter minus 2 sides combined. (5 points)

Given the box plot, will the mean or the median provide a better description of the center? (1 point)
