Answer quick
use the grouping method to factor:

The answer is B

(x^3 + x^2) + (5x + 5)

Factor out common factors from the binomials

x^2(x + 1) + 5(x + 1)

Now you factor out the greatest common binomial in the remaining expression

(x +1)(x^2 + 5)

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.
