Love2Smile Posted August 30, 2011 Share Posted August 30, 2011 6(n+8) That is the problem. It says to evaluate each expression. Don't you need to know what "n" is to evaluate?? Thanks! Quote Link to comment Share on other sites More sharing options...
April in CA Posted August 30, 2011 Share Posted August 30, 2011 Hi! Regardless of what "n" is, you can evaluate the expression as 6n + 48. Whatever n is, this will always be true for this expression. Hope this helps! Blessings, April Quote Link to comment Share on other sites More sharing options...
Kathleen. Posted August 31, 2011 Share Posted August 31, 2011 I'll take a stab.... 6(n+8) Multiply 6n + 48 divide both sides by 6 n=8 hope that helps Quote Link to comment Share on other sites More sharing options...
Teachin'Mine Posted August 31, 2011 Share Posted August 31, 2011 Kathleen that would work if it was 6n = 48. I think that what April showed is what they're looking for. Quote Link to comment Share on other sites More sharing options...
kiana Posted August 31, 2011 Share Posted August 31, 2011 Are you sure that it didn't tell you what 'n' was in a previous problem or something? The reason I'm asking is that I have always seen 'evaluate' used when you were asked to find a specific value, and 'simplify' used when they mean to use the distributive property to expand something. However, if this is in a chapter on the distributive property, I'd assume that's what they meant. Quote Link to comment Share on other sites More sharing options...
ChrissySC Posted September 1, 2011 Share Posted September 1, 2011 6(n+8) (6*n)+(6*8) 6n+48 6n+48-48=-48 6n=-48 6n/6=-48/6 n=48/6=8 Quote Link to comment Share on other sites More sharing options...
PIE! Posted September 1, 2011 Share Posted September 1, 2011 6(n+8)(6*n)+(6*8) 6n+48 6n+48-48=-48 6n=-48 6n/6=-48/6 n=48/6=8 close - but you can't just add an = if the original problem doesn't have one to begin with. The above is starting with the assumption that 6(n+8)=0. aAll you can do is distribute it to 6n+48, unless there is more info somewhere else.

The best you can do is 6n + 48 without other info. Quote Link to comment Share on other sites More sharing options...
Jann in TX Posted September 2, 2011 Share Posted September 2, 2011 An expression does not have an = sign. You can 'simplify' the expression. It is possible to evaluate the expression IF you are give the value of the variable. In your case 6n + 48 is all that you can do with it.

You know, I had forgotten about that!:lol: It has been several years since algebra, and I have since moved to everything with an assignment operator, LOL Ty for the reminder!

Pretty in Pink Posted September 4, 2011 Share Posted September 4, 2011 The answer is 6n+48, though the instructions should have told you to simplify rather than evaluate, unless the value of n was given previously. Quote Link to comment Share on other sites More sharing options...
