Let f(x) = 7x² - 5x + 3 and g(x) = 2x² + 4x -6

part a: find f(x) + g(x)

part b: find f(x) - g(x)

part c: find g(x) - f(x)

sorry for asking with a pretty simple thing but i'm just so tired, if would a lot!

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.

C, e, and a (hope it )
