Sean Delgado · Answer 2

Answer: (a) 9

Step-by-step explanation:

1st multiple of 3: 1 (3x)

2nd multiple of 3: 2 (3x)

3rd multiple of 3: 3 (3x)

Sum = 4 (1st multiple of 3) + 6

1 (3x) + 2 (3x) + 3 (3x) = 4 (3x) + 6

3x + 6x + 9x = 12x + 6

18x = 12x + 6

6x = 6

x = 1

Largest (3rd) multiple is: 3 (3x)

= 9x

= 9 · 1

= 9
