Question #e5ee3

Answer 1

`18, 36, 54, 72, 90, 108, 126, 144`

Explanation:

`8 xx 1=8`
`8xx 2 = 36`
`8xx3=54`
etc.
`8xx8=144`

Answer 2

`18," "36," "54," "72," "90," "108," "126," "144)`

Explanation:

Multiplying is a short way of writing repeated addition..

Instead of `7+7+7+7+7`, we can write `5xx7`

`7+7+7+7+7 = 5 xx7 =35`

To find the multiples of `18`, just keep adding on another `18`

`18= 1xx18 =color(blue)(18`

`18+18 = 2 xx 18 =color(blue)(36`

`18+18+18 =3xx18 =color(blue)(54`

`18+18+18+18 = 4 xx 18=color(blue)(72`

and so on ....

The first eight multiples are:

`color(blue)(18," "36," "54," "72," "90," "108," "126," "144)`

You might notice they are all the even multiples of `9`
