Part A: We know that the equation for finding the area of a triangle is 
; we also know that 
and 
, so the only thing we need to do is replacing those values into our Area equation and solve for x:
Now the only thing left is factor the quadratic polynomial:
W can conclude that the area of our triangle is
Part B: Our polynomial has three terms, so is a trinomial; also, our polynoal only has one variable,
, and the largest exponent of that variable is 2; therefore is a degree 2 polynomial. In summary, we have a trinomial of degree 2.
Part C: Part A demonstrate the closure property of polynomials because after multiplying tow polynomials we obtained another polynomial.

Answer:
The null and alternative hypotheses are:
Under the null hypothesis, the test statistic is:
Therefore, the test-statistic is
Now the F critical value at 0.02 significance level for df1 = 10- 1 =9 and df2 = 16 - 1 =15 is:
Since F statistic is greater than the F critical value, we therefore, reject the null hypothesis and conclude that there is sufficient evidence to support the claim that there is a difference in the variation in the listening times for men and women.
