Question

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

Answer 1

Answer:

$-17s + 23$

Step-by-step explanation:

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

$- 3(s - 10) = - 3s - 3 \times ( - 10)$

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

$- 3s + 30 - 14s - 7$

$- 17s + 30 - 7$

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

Answer 2

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

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