5. Which of the following statements is true? A) -42 = -16 = (-4)2

B) -42 = 16 = (-4)

C) -42 = -16 and (-4)2 = 16

The answer is C, not A. Exponent without parentheses on a negative base will be negative, and exponent with parentheses on a negative base will be positive.

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.
