Answer 1

To be able to determine the answer to this question, we must simplify each choice and see whether they end up with 18x - 6.

We get,

A.) 16.4x - 6 + 1.6x

`16.4x-6+1.6x`
`18x-6`

B.) 2(9x - 3)

`2\mleft(9x-3\mright)`
`(2_{}\mleft(9x)+(2)(-3\mright)`
`18x\text{ - 6}`

C.) 3(9x - 2)

`3\mleft(9x-2\mright)`
`(3)\mleft(9x)+(3)(-2\mright)`
`27x\text{ - 6}`

D.) 12x - 6 - 6x

`12x-6-6x`
`6x-6`

E.) 6(3x - 1)

`6\mleft(3x-1\mright)`
`(6)\mleft(3x)+(6)(-1\mright)`
`18x\text{ - 6}`

Therefore, the answer is A, B and E
