a million) you want to hit upon a polynomial at the same time as squared equals 25x^2-40x+16 (5x-4) works; (5x-4)(5x-4) = 25x^2-40x+16. 2) the accurate, h equals two times the bottom, b minus one, so h=2b-a million and the section a = bh/2, so a = 33 = b(2b-a million)/2 for this reason 33 = b^2-b/2 Now multiply each and each aspect by ability of two to get sixty six = 2b^2-b set up to 2b^2-b-sixty six=0 and ingredient or use the quadratic formula to locate (b-6)(2b+11)=0 considering the fact that in elementary words the first time period (b-6) corresponds to a real international probability of a tremendous b of six, this is the answer. for this reason b=6, h=11.

i dont know the rest sorry <3
