Answer: 4 x (5 minus 4 y) or [tex]4x(5-4y)[/tex]
Step-by-step explanation:
We have the following expression:
[tex]20x-16xy[/tex]
In addition, we are told the common factor is [tex]4x[/tex]. Let's apply it in the expression and simplify:
[tex]20x-16xy=4x(5-4y)[/tex]
To understand it better:
[tex]20x=(4x)(5)[/tex] and [tex]16xy=(4x)(4y)[/tex]
Then, the correct option is:
4 x (5 minus 4 y)
