1 point
B={x|x is the multiple of 5}
B={x|x=5n, n€N}
B={x|x=5n, n€N, n<9}
B={x|x=5n, n€N, n<8}

Answer 1

Answer:

B={x|x=5n, n€N, n<9}

Step-by-step explanation:

5n mean 5 times of n, so if n is 9 then x is 5 times 9 which is 45 .

40<45 so it satisfies the inequation and multiples of 5 till 40 are in the set
