The word POWER has 5 different letters ( n = 5 ):
P ( n ) = n !
P ( 5 ) = 5 ! = 5 * 4 * 3 * 2 * 1 = 120
Answer:
A ) 120
1) subtract 2y in both sides: (7y-2y)-6=(2y-2y)+8 which is 5y-6=8
2) Add 6 to both sides: 5y(-6+6)=8+6 which is 5y=14
3) Divide 5 on both sides: 5y/5=14/5 which is y=14/5 or y=2.8 or y=2 4/5
Use the distributive property backwards.
xp+yp=z become p(x+y)=x, which solves to p=x/(x+y)
