One craft stick is 5 centimeters long and the other is 8 centimeters long. which of the following cannot be the length of the craft stick that she will use for the third side of the triangle? 14

14 centimeters, because it is a cm longer than the total length of the other 2 craft sticks. Even if the 5cm and 8cm sticks were laid out in a straight line (ie. with a 180° angle between them) they still would not be able to touch both ends of the 14cm stick.

1. We can get Equation (B) from Equation (A) by multiplying it with 4.

therefore the correct option would be :

C. Multiply / Divide only one side by a non-zero constant.

2. A. Yes, they are equivalent since we can get Equation (B) from Equation (A) by multiplying it with 4.
