Answer:
1. 4x + 6
2. -15x + 11
5. -x + 4
6. -4x + 7
9. 5x - 2
12. x + 16
Step-by-step explanation:
Remove the parenthesis for each one so everything's out in the open. Next, you group like terms. The numbers with variables on one side, and the other numbers on the other side. For example:
x + 3x - 2 + 8
Then, you combine like terms:
4x + 6
That's mostly how you do each one.
Expanded: 8.000 + .500 + .010 + .007
Word Form: eight ones, five tenths, one hundredth, seven thousandths
Hope this helps!

Answer:
A - 2 feet
Step-by-step explanation:
We know that the tank is a rectangular prism which means the volume is equal to length*width*depth

30/5 = 6
6/3 = 2
therefore, the depth of the tank has to be 2 feet (A)
