How do you simplify the expression 9m-7m+2m

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

Item 1 solve for s. s+24=90 −114 −66 66 114

Aline passes through the point (–7, 5) and has a slope of 1/2 which is another point that the line passes through?
