Question

Rewrite in simplest terms: -3(s – 10) + 7(-2s – 1)

Answer 1

-3(s-10)+7(-2s-1)

-3s+30+(-14s-7)

Answer 2

`-17s + 23`

Explanation:

`- 3(s - 10) + 7( - 2s - 1)`

`- 3(s - 10) = - 3s - 3 * ( - 10)`

`- 3s + 30 + 7( - 2s - 1)`

`- 3s + 30 - 14s - 7`

`- 17s + 30 - 7`

`\boxed{\green{= - 17s + 23}}`
