question\nrewrite in simplest terms: -9(-n + 8) - 9(-8n - 2)

Explanation:

Step1: Apply distributive property

$-9(-n + 8)=(-9)\times(-n)+(-9)\times8 = 9n-72$ and $-9(-8n - 2)=(-9)\times(-8n)+(-9)\times(-2)=72n + 18$

Step2: Substitute back and combine like - terms

$(9n-72)+(72n + 18)=(9n+72n)+(-72 + 18)$ $=81n-54$

Answer:

$81n - 54$
