Step-by-step explanation: The first step when factoring any polynomial is to factor out the GCF. The GCF is the greatest common factor for all the terms of the polynomial. By factoring out the GCF first, the coefficients and constant term of the polynomial will be reduced.
Answer:
Option A.
Step-by-step explanation:
The given equation is
Liliana wants to write an equivalent expression.
It can be written as
Using commutative property, we get
![[\because A+B=B+A]](https://tex.z-dn.net/?f=%5B%5Cbecause%20A%2BB%3DB%2BA%5D)
Using associative property, we get
![[\because A+(B+C)=(A+B)+C]](https://tex.z-dn.net/?f=%5B%5Cbecause%20A%2B%28B%2BC%29%3D%28A%2BB%29%2BC%5D)
Using distributive property, we get
![[\because An+Bn=(A+B)n]](https://tex.z-dn.net/?f=%5B%5Cbecause%20An%2BBn%3D%28A%2BB%29n%5D)
Using addition property, we get
Therefore, the correct option is A.

Each roll is 9' long,
length of each roll = 9' * (12"/foot) = 108"
Each ribbon piece = 15", so number of ribbons per roll
=108/15=7 with 3" left over, which is assumed not possible to be joined with other pieces.
Therefore, with 5 rolls, there are 7*5=35 pieces of ribbon, with 5 pieces or 3" left over.
