Option 1 - ![6(x+5)](/tpl/images/0483/3577/61f92.png)
Step-by-step explanation:
To find : Which algebraic expression is a product with a factor of 6?
Solution :
1) ![6(x+5)](/tpl/images/0483/3577/61f92.png)
In this algebraic expression 6 is a factor of 6 and is with the product of (x+5).
2) ![6+x-9](/tpl/images/0483/3577/d0133.png)
![6+x-9=x-3](/tpl/images/0483/3577/b7ce7.png)
In this algebraic expression there is no product.
3) ![6x-9](/tpl/images/0483/3577/de6d3.png)
In this algebraic expression there is no product.
4) ![9x\div 6](/tpl/images/0483/3577/08afd.png)
![9x\div 6=\frac{3x}{2}](/tpl/images/0483/3577/c95e4.png)
In this algebraic expression there is no product.
Therefore, Option 1 is correct.
