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)

Vikram is studying the square pyramid below. on st to find the surface area of the pyramid, in square inches, vikram wrote (33.2) (34 ikram wrote (33.2)(34.2)+43(34.2)(284) what error did vikram make? o he used the same expression for the area of all four lateral faces. he used the wrong expression to represent the area of the base of the pyramid. o he used the wrong value as the height when he found the area of the lateral faces. he used an expression for surface area that only finds the total area of three faces.
