Evaluate |-3x + 7|given x = 6.

So first take triple 3 which would be 3+3+3 or 3x3.
Then take double 8 which would be 8+8 or 8x2.
So all you need to do is write it in the associative property.
So it would look like this:
(3x3)+(8x2)= 25
   9   +  16
Because 3x3 is 9 and 8x2 is 16 so you just need to add them to get the product.
