Rachel’s friend yassi has to write 3(b + s) pages for reports. use properties of operations to determine whether this expression is equivalent to the expression for the number of pages rachel has to write.

3b+3s

Step-by-step explanation:

The first part of this question is:

Rachel needs to write 3 book reports with b pages and 3 science reports with s pages during the school year. How do you write an algebraic expression for the total number of pages Rachel will need to write?

This means Rachel has to write 3b+3s pages

Now, if Yassi has to write 3(b + s) pages, we can use the distributive property and the result is:

3(b + s)=3b+3s

Which is the same number of pages Rachel has to write.
