Final answer:
To collect like terms and arrange them in descending order, combine the terms and then organize them.
Explanation:
To collect like terms and arrange them in descending order, we first need to combine the terms with the same variable raised to the same power. Let's rearrange the terms: 9x6, 5x8, 8x7, 6x6, 7x7, 6x8.
Combining terms, we have: 9x6 + 8x7 + 6x8 + 6x6 + 7x7 + 5x8 = 54x + 56x + 48x + 36x + 49x + 40x = 283x
Now, we can write the terms in descending order: 283x.
