\large\bold{{Is}}

 \bold{{1.)\:10 \times (6 + ( - 2)) = 10 \times 6 + 10 \times ( - 2)}}

 

 \bold{{2.)\:( - 15)(( - 7) + ( - 1)) = ( - 15) \times ( - 7) + ( - 15)( - 1)}}

 

\large\bold\color{yellow}{{{\: \:\: \:\:\:\:\: \:\:\: \: \: \: \:\:\: \: \:\: Solution}}}

 

\bold{{1.)\:10 \times (6 + ( - 2)) = 10 \times 6 + 10 \times ( - 2)}}

 

\Rightarrow\bold{{10\times4=60+(-20)}}

 

\Rightarrow\bold{{40=60-20}}

 

\Rightarrow\bold{{40=40}}

 

\bold{{2.)\:( - 15)(( - 7) + ( - 1)) = ( - 15) \times ( - 7) + ( - 15)( - 1)}}

 

\Rightarrow\bold{{(-15)(-7-1)=(-15)\times8}}

 

\Rightarrow\bold{{(-15)(-8)=120}}

 

\Rightarrow\bold{{120=120}}
