The 2 negatives cross out themselves so then toy are just adding. Your answer is 10.

i will not do your homework but i well help you through your homework

you need to combine like terms. so your answer would be 11m+4

if you have a scientific calculator or the TI-30XS version then you would hit the button 2nd and then the carrot symbol. then you would type in your question. If you dont have a calculator then you try multiply 2 of the same numbers and if you get your answer right then there you go. it is much easier to do it with a calculator. I hope this was helpful for you.

These are easy you just need to think of the equation like a heart. you would take your mass over your volume and whatever it is, is your answer. in this case it would be 9.
