Step-by-step explanation:

`(b(5a + 7b))/(b +2b)` ;

Simplify the "denominator" ; → (b + 2b = 1b + 2b = 3b) ;

and rewrite:


`(b(5a + 7b))/(3b)` ;

Cancel out the "b" in the "numerator" to a "1" ;
and cancel the "3b" in the "denominator to a "3" ;

{since: "b ÷ b = 1 "; and since: "3b ÷ b = 3" } ;

and rewrite as:

`(5a + 7b)/(3)` ;

→ which is: Answer choice: [D]: "
`(5a + 7b)/(3)` " .
