The given expression is:
[tex](3\cdot x)\cdot5[/tex]Substitute the given value x=-1/5 into the expression:
[tex](3\cdot-\frac{1}{5})\cdot5[/tex]Recall that the associative property of multiplication is:
[tex](a\cdot b)\cdot c=a\cdot(b\cdot c)[/tex]Apply this to the given expression gives:
[tex](3\cdot-\frac{1}{5})\cdot5=3\cdot(-\frac{1}{5}\cdot5)[/tex]Next do the multipication in the parentheses:
[tex]\begin{gathered} 3.(-\frac{1}{5}\cdot5) \\ =3\cdot(-1) \end{gathered}[/tex]Hence, the correct option is the second option.
