Which example shows the identity property of multiplication? 1. a(b + c) = ab + ac

2. (a + b) + 9 = a (9 + b)

3. a + a + a = 3a

4. a(1) = 1

Number 2 I think that’s it

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.

A. but. i don’t nohxbzbz
