What is the prime factorization for 58

Nnnnneeedd 1.find the residual if you know the actual number is 5.2 and the predicted value is 4.8

Me! i really need to get this right before 9. prove the divisibility of 7^6+7^5-7^4 by 11. use factoring so you get a number times 11. just tell me the number. i need this done asap

Which property was used to simplify the expression? 3c+9 +4c=3c+4c+9
