Step-by-step explanation:
This is because, in order to simplify, first you need to distribute the 2 into the x+5. So, you get 2x+10. Then you get 9x-3+2x+10. The 9x and 2x combine to get 11x. The -3+10 combine to get 7. So you have 11x+7.

sigma=sqrt(n*p*(1-p))=sqrt(100*.7*.3)=4.58
so we're looking at 70+4.6 and 70-4.6.
