-10n-3m because the two negatives (-9nand -n) are like terms and they become -10n because the negative n is basically -1n the -3m is there by itself with no other like terms so it stays the same
Answer: -4.5n - 4
Calculation/Explanation:
Distribute;
9 + (0.5)(7n) + (0.5)(-26) + -8n
= 9 + 3.5n + -13 + -8n
Combine Like Terms:
= 9 + 3.5n + -13 + -8n
= (3.5n + -8n) + (9 + -13)
<span>= -<span><span><span>4.5n </span></span>+ -<span><span>4</span></span></span></span>
