Question

Rewrite in simplest terms: -9(8n+4p)-7p-2(-10p-9n)

Answer 1

Don’t know if this is what you want but the simplest answer I got was:

-54n-23p

Answer 2

Explanation:

Let's simplify it step-by-step.

−9(8n+4p)−7p−2(−10p−9n)

Distribute:

=(−9)(8n)+(−9)(4p)+−7p+(−2)(−10p)+(−2)(−9n)

=−72n+−36p+−7p+20p+18n

Combine Like Terms:

=−72n+−36p+−7p+20p+18n

=(−72n+18n)+(−36p+−7p+20p)

=−54n+−23p
