The lengths of three sides of a trapezoid are shown below:
side 1: 11z2 − 4z + 2
side 2: −2z + 3 + 12z2
side 3: 3 − 3z + 13z2
the perimeter of the trapezoid is 5z3 + 40z2 + 7z − 15.
part a: what is the total length of sides 1, 2, and 3, of the trapezoid?
part b: what is the length of the fourth side of the trapezoid?
part c: do the answers for part a and part b show that the polynomials are closed under addition and subtraction?

Asix-sided die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. in the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, 5 times, and 7 times. the experimental probability of rolling a 3 is 10 %, which is approximately % more than its theoretical probability. (round off your answers to the nearest integer.)
