Answer: 1)
a combination
b permutation
c permutation
d permutation
2)
B coz 6 and 11 is the only combination which can have 462 possibilities as they r both factors of 462
12×50=600
12×49=588
600-12=588
4x-6= 22
Move -6 to the other side.
Sign changes from -6 to +6.
4x-6+6= 22+6
4x= 22+6
4x= 28
Divide by 4 for both sides
4x/4= 28/4
x= 7
Answer : x= 7
