5x^3 + 3x^2 - 7x + 10 -3x^3 + x^2 - 4x + 1
= 2x^3 + 4x^2 - 11x + 11combine like terms.

hope that helps

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.

Bis the correct answer
