Answer:
48x^2-10x-72
Step-by-step explanation:
What you do is the distributive property but at one time.
So you will multiply 6x to all the numbers. Then you will multiply -8 to all the numbers.
6x(3x+5x+9)=18x^2+30x^2+54x.
-8(3x+5x+9)=-24x-40x-72.
You will then add them together to get
48x^2-10x-72 as your answer.
