Respuesta :

The given expression is,

[tex]45-105x[/tex]

The factors of 45 are 1,3,5,9,15,45

The factors of 105 are 1,3,5,7,15,21,35,105.

Thus, we can infer that 15 is the greatest common factor, therefore, we can write,

[tex]45-105x=15(3-7x)[/tex]

Also, 5 is a common factor, therefore, we can write,

[tex]45-105x=5(9-21x)[/tex]

Thus, A and B are correct.
