Question

How do you write the phrase as a variable expression: the product of -6 and the sum of a number and -1?

Answer 1

`-6(x-1) or -6` x`(x-1)`

Explanation:

You can consider "the sum of a number and -1" as a single entity.
So the question is asking the product of -6 and sum of a number and -1

`=> -6` x (the sum of a number and -1)

Since, we don't know what the number is, we assume it as a variable (say x).

`=> -6` x `(x+(-1))`
`=> -6` x `(x-1)`
Or, `-6(x-1)`

Hence the answer.
