Answer:
One piece is
inches and another piece is
inches
Step-by-step explanation:
Let smaller piece length be 
Let larger piece length be 
Since total of two pieces is 43, we can write:

Also, one piece is twice as long as the other (so longer piece is definitely twice as the short piece), we can write:

<em>Substituting equation 2 into equation one, we can solve for s:</em>

<em>Thus longer piece is:</em>

Answer:
4
Step-by-step explanation:
you can do
horizontal
diagonal (both ways)
vertical
Two 2 1/3 + 2 1/3 = 4 2/3
8/1 - 4 2/3 =
14/3 - 8/1 = 6/2
