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
[tex]16.4x-6+1.6x[/tex][tex]18x-6[/tex]
B.) 2(9x - 3)
[tex]2\mleft(9x-3\mright)[/tex][tex](2_{}\mleft(9x)+(2)(-3\mright)[/tex][tex]18x\text{ - 6}[/tex]
C.) 3(9x - 2)
[tex]3\mleft(9x-2\mright)[/tex][tex](3)\mleft(9x)+(3)(-2\mright)[/tex][tex]27x\text{ - 6}[/tex]
D.) 12x - 6 - 6x
[tex]12x-6-6x[/tex][tex]6x-6[/tex]
E.) 6(3x - 1)
[tex]6\mleft(3x-1\mright)[/tex][tex](6)\mleft(3x)+(6)(-1\mright)[/tex][tex]18x\text{ - 6}[/tex]
Therefore, the answer is A, B and E
