Answer:
So, the answer is 20
Step-by-step explanation:

Long piece = 5+ 2•short piece
Long piece +short piece=17
Let short piece be x and long piece y
Rewrite the relations given
y= 5+2• x
y+x=17 so y=17- x
5+2•x=17-x
2x+x=17-5
3x=12
X=12/3=4 (short piece) feet
y=17-4=13 (long piece) feet
The correct answer is A. Forty thousand, five hundred seventeen.
