Question

9 added to the product of two consecutive multiples of 6 gives 729 .what are the line numbers?

Answer 1

Answer:

4 and 5

Step-by-step explanation:

let 2 consecutive multiples be 6x and 6 ( x+1 )

9+6x.6 . (x+1)=729

36.x.x+1=729-9

x.x+1=720/36

x.x+1=20

the possible factors are (1,20) (2,10) (4,5)

the ANS is 4 and 5 ( since , consecutive multiples ) .
