9.74 feet
Step-by-step explanation:
the formula for finding a hypotenuse is 
. We can rearrange that to get: 
. So: 49 + b^2 = 144. We get the square root of 95, AKA around 9.74.
Anser is B). Subtract smallest number

Well how long is the ribbon? I'm not asking for the dollar amount, I will answer your question if you can tell me the length of the ribbon. No one can figure it out unless you give the total length.
So first off, remember the formula for the area of a rectangle. it's length time width right? or, you could think that A= 2 things multiplied together. how can we simplify x^2 - x -72 to equal two things multiplied together? well, we can factor it! We know that one of the factors is x+8 right? so what's the other factor? it would be x-9. so, we know width is x-9. I'm not sure if you need an actual value for width. if so, I could probably go further.
