Guys if u need help with math download an app called Gauthmath and put this code in P9EJ5H for unlimited answers so basically u download it and it will ask for a code u type P9EJ5H and then it will open and u snap a picture of the problem and the tutor will answer ur question. It works for physics, math, and chemistry I will mark brainliest if u use the code because I will get a notification and we will both earn 10 tickets because I referred u to this app and u used it so we will both benefit from it
