OK, so we know that m=3 and p=10. All we have to do is change the problem a little and then solve it! :)

when m=3 and p=10 the problem would be this: 3x3x2+2x10x2-15.
anonymous
  • anonymous
so all i would have to do is multiply those numbers then add & subtract, right?
anonymous
  • anonymous
Right! PEMDAS. Do the multiplication first, then the adding, and last the subtracting.

When you get the answer let me know what it is, please. I just want to make sure you didn't make any mistakes. :)
anonymous
  • anonymous
okay i got 43.. but the answer is not one of the choices
anonymous
  • anonymous
Ok, that is the wrong answer. Now I am going to break it down for the problem to be easier Do 3x3x2, then do 2x10x2. Let me know your answer with those two and then we can keep going.
anonymous
  • anonymous
3x3x2= 18 & 2x10x2= 40 ?
anonymous
  • anonymous
Before we go on can you pls post the multiple choices?
anonymous
  • anonymous
the choices are 27 200 212 & 225
anonymous
  • anonymous
Are you positive these are the multiple choice answers for this particular problem?
anonymous
  • anonymous

OHHHH! It's with exponents, and it took that away when you copied and pasted it! Ok here is what the problem really and truly should be like: 3x3^2+2x10^2-15. So first are exponents. Figure out what 3^2 is, and what 10^2 is.
anonymous
  • anonymous
3^2 would be 9 & 10^2 would be 100 .. right?
anonymous
  • anonymous
right! :) Now what you do is 3x9, and 2x100.
anonymous
  • anonymous
okay.. 3x9 is 27 & 2x100 is 200
anonymous
  • anonymous
great! Now what is 27+200-15?
anonymous
  • anonymous
212, omg i feel so stupid it was simple.. thank you so much for helping me though! :)
anonymous
  • anonymous
Any time, and don't feel stupid sometimes we just need that little help to remember! Also, sorry for the confusing and how long it took. Good luck!! :)
anonymous
  • anonymous
