Given that: A # B # C = 2A − 3B + 5C\displaystyle \:A\,\#\,B\,\#\,C \:=\: 2A\,-\,3B\,+\,5CA#B#C=2A−3B+5C, what is the value of 3 # (−2) # 4\displaystyle 3\,\#\,(-2)\,\#\,43#(−2)#4 ? Click to expand... They told us that A # B # C\displaystyle A\,\#\,B\,\#\,CA#B#C means: . . "2 times the first number, minus 3 times the second, plus 4 times the third". So 3 # (−2) # 4\displaystyle \,3\,\#\,(-2)\,\#\,43#(−2)#4 means: 2(3) − 3(−2) + 4(4) = 6 + 6 + 16 = 28\displaystyle \:2(3)\,-\,3(-2)\,+\,4(4)\;=\;6\,+\,6\,+\,16\;=\;282(3)−3(−2)+4(4)=6+6+16=28
