Question

Can you show me how to do this I’m so confused and it’s due today and I can’t fail this class please help!! I’m in 8th grade just so know

Answer 1

The distribution property said:

`a\cdot(b+c)=a\cdot b+a\cdot c`

Then:

`\begin{gathered} -6\cdot(a-8)=-6\cdot a+(-6)\cdot(-8) \\ -6\cdot(a-8)=-6a+48 \end{gathered}`
`\begin{gathered} 4\cdot(1+9x)=4\cdot1+4\cdot(9x) \\ 4\cdot(1+9x)=4+36x \end{gathered}`
`\begin{gathered} 6\cdot(-5n+7)=6\cdot(-5n)+6\cdot7 \\ 6\cdot(-5n+7)=-30n+42 \end{gathered}`
`\begin{gathered} (9m+10)\cdot2=9m\cdot2+10\cdot2 \\ (9m+10)\cdot2=18m+20 \end{gathered}`
`\begin{gathered} (-4-3n)\cdot-8=-4\cdot(-8)+(-3n)\cdot(-8) \\ (-4-3n)\cdot-8=32+24n \end{gathered}`
`\begin{gathered} 8\cdot(-b-4)=8\cdot(-b)+8\cdot(-4) \\ 8\cdot(-b-4)=-8b-32 \end{gathered}`
`\begin{gathered} (1-7n)\cdot5=1\cdot5+(-7n)\cdot5 \\ (1-7n)\cdot5=5-35n \end{gathered}`
