Ineed really fast, will give brainliest what is the value of the expression when a = 4 and b = 2? 2a^3+ 2b^2 a. 48 b. 80 c. 120 d. 136

Hello! The answer would be D.136. :) 

2(4 3)+2(2 2)2(4 3)+2(2 2)

(The 3 is to the 3rd power, and the 2 in parenthesis is to the 2nd power. If that makes sense. 

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.
