The given expression is,
[tex]-3\mleft(-5y-4w+2\mright)[/tex]
Apply the distributive property:
[tex]\begin{gathered} \: m\mleft(a+b+c\mright)=ma+mb+mc \\ -3\mleft(-5y-4w+2\mright)=-3\mleft(-5y\mright)-3\mleft(-4w\mright)-3\times\: 2 \end{gathered}[/tex]
Simplify
[tex]-3\mleft(-5y\mright)-3\mleft(-4w\mright)-3\times\: 2=15y+12w-6[/tex]
Hence, the answer is
[tex]15y+12w-6[/tex]
