Julie cannot be right. That's because if you add three odd numbers together, <em>you always get an odd number. </em>The number 50 is an Even number.
Let's try adding 3 odd numbers together a couple of times...3 + 3 + 3 = 9 5 + 1 + 5 = 11 7 + 3 + 5 = 15
We tried 3 examples, we could not get any even number. So,
Julie's claim is wrong.
Depends on how the papers are connected. if they are connected with the 7cm side joining each other, use solution one. if they are connected with the 9cm side joining each other, use solution two.
perimeter of edges of sign= 2 [(9x3)+7]
= 68 inches
left over= 144-68
= 76 inches
OR
perimeter of edges of sign= 2[(7x3)+9]
= 60 inches
left over= 144-60
= 84 inches
Do you have a picture that shows the graphs
