Alex has a piece of
ribbon that is 45 feet
long. He cuts the ribbon.
Now he has 39 feet of
ribbon. How many feet of
ribbon did Alex cut off?

an equation to solve.
Show your work.

He cut of 6 feet of ribbon.

Step-by-step explanation:

45

-39

  6

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
