f(x)=3b+3s. This is the answer ,because b and s is like your x. They're what you multiply by to get the number of pages. So if b and s equaled 3 you would plug 3 into b and s. So it'd be f(x)= 3(3)+3(3) which equals your answer

Answer: 3 b + 3 s

Step-by-step explanation:

Hi, to answer this question we have to write an algebraic expression with the information given:

She needs to write:

  • 3 book reports with b pages
  • 3 science reports with s pages  

So, the total number of pages is equal to the product of the number of book reports(3) and the number of pages of each book report (b) , plus the product of the number of science reports (3) and the number of pages of each science report (s).

Mathematically speaking:

3 b + 3 s
