Answer: 2g - 32
Explanation:
-2 (3g - 8g + 8) - 9g - 2 (3g - 8g + 8) - 9g
First step is to use the distributive property to distribute 2.
The expression is now:
-6g + 16g - 16 - 9g - 6g + 16g - 16 - 9g
Now you put the like terms together..
-6g + 16g - 9g - 6g + 16g - 9g -16 - 16
All that is left to do is combine them!
(-6g + 16g - 9g - 6g + 16g - 9g) + (-16 - 16)
2g + (-32)
2g - 32
Hope that helped!
