4-[6(3x+2)-x]+4 order of operations
weqwewe [10]

Answer:

-4 - 17x

Step-by-step explanation:

Anything enclosed in parentheses must be done first if possible.  (3x + 2) is inside two sets of parentheses, but nothing can be done with 3x + 2.  

Multiplication must be done next.  [6(3x+2)-x] becomes 18x + 12 - x, or

17x + 12.

Now we have 4 - 17x - 12 + 4.  Combining like terms through addition and subtraction, we get 4 - 12 + 4 - 17x, or -4 - 17x.

Alex73 [517]

In the pool, the rail of the table can be considered a rebound line as the definition suggest the table's rail can be used as a rebound line.

<h3>What is a rebound line?</h3>

Water is released from the earth when it is squeezed or compacted by some force. As a further stage, the stress in the soil is removed, allowing the soil sample to expand back to its original size.

The soil will try to reclaim some of the stress it has lost after the stress has been released. Rebound is the word for this procedure.
