When cutting wood with a saw, a carpenter must take into account the thickness of the saw blade. suppose that from a piece of wood 42 in. long, a carpenter cuts a 17 1/2 in. length with a saw blade that is 1/8 in. thick. how long is the piece that remains?

  24 3/8 in.

Step-by-step explanation:

The amount that remains is the original amount less the cut off length and the width of the saw:

  42 in - 17 1/2 in - 1/8 in = 24 3/8 in . . . remaining

each side has a different length.  

step-by-step explanation:

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
