anonymous · Answer

What r u trying to figure out?

anonymous · Answer

wait nvm, lol

anonymous · Answer

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! :)

anonymous · Answer

when m=3 and p=10 the problem would be this: 3x3x2+2x10x2-15.

anonymous · Answer

so all i would have to do is multiply those numbers then add & subtract, right?

anonymous · Answer

Right! PEMDAS. Do the multiplication first, then the adding, and last the subtracting.

anonymous · Answer

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 · Answer

okay i got 43.. but the answer is not one of the choices

anonymous · Answer

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 · Answer

3x3x2= 18 & 2x10x2= 40 ?

anonymous · Answer

Before we go on can you pls post the multiple choices?

anonymous · Answer

27
200
212 
& 225

anonymous · Answer

anonymous · Answer

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 · Answer

3^2 would be 9 & 10^2 would be 100 .. right?

anonymous · Answer

right! :)

Now what you do is 3x9, and 2x100.

anonymous · Answer

okay.. 3x9 is 27 & 2x100 is 200

anonymous · Answer

great! 

Now what is 27+200-15?

anonymous · Answer

212, omg i feel so stupid it was simple.. thank you so much for helping me though! :)

anonymous · Answer

anonymous · Answer
