PLEASE I NEED HELP WITH THIS ANSWER; When the terms of a polynomial in x are arranged from the highest to the lowest powers of x, the polynomial is in descending order. Simplify the following polynomial in descending order then evaluate for n = -0.25. 6 - (2n^2 + n) - (5n+n^2-6) - ( 4n+2n^2 - 11 )

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
