What is the value of the expression –4x3 when x = –2? A. –24 B. –32 C. 32 D. 24
timurjin [86]
Answer to your question would be 
c. 32
Because you would first have to multiply -4 and -2, and a negative times a negative times a negative equals a positive so -4 times -2 = 8 and then 8 times 3 equals 32 so the answer would be 32.
