Answer:
n how many ways can a president, vice president, and a secretary be chosen? It is 12X11X10. Permutation of n things taken r at a time: nPr=n!/(n-r)! 12P3=12*11*10*9!/9!= 12*11*10=1320 ways.
Step-by-step explanation:
We know that we can take 4 out of (-16x + 8) [ we know this because we can divide 16 by 4 ( to get 4 ) and we can divide 8 by 4 ( to get 2 ) ]
we can factor out a 4 then from the parentheses to get 4(-4x + 2), but since we are multiplying by 1/4 we get
1/4(4)(-4x + 2), and since 1/4 * 4 = 1, our final answer is
-4x + 2
