Best ResponseYou've already chosen the best response.1think of the parens as a package 10( 3x 1) means you have 10 "packages" of 3x1 if you have 10 of (3x1) how many 3x's do you have ? how many 1's do you have ?

Best ResponseYou've already chosen the best response.0that would mean there are 30 3x's and 10 1's ?

Best ResponseYou've already chosen the best response.1you would have 10 3x's and 10 of 1's we show that by multiplying: 10*3x + 10* 1 (3x means 3*x, and 10*3*x is the same as 30*x or 30x)

Best ResponseYou've already chosen the best response.1in other words 10(3x 1) is 30x + 10 which can be written 30x10

Best ResponseYou've already chosen the best response.1you will use this "rule" a lot. (called distributive law) you will also use it backwards,i.e. be able to undo the multiply and change 30x 10 to 10(3x1)

Best ResponseYou've already chosen the best response.1the answer to this problem is mistake was to not multiply both terms by the "factor"

Best ResponseYou've already chosen the best response.1yes, they did 10(3x1) > 10*3x 1 which means they did not do 10*1

Best ResponseYou've already chosen the best response.1I would say "they did not distribute the 10" it is the number out front (the 10), which they called the "factor" which is "distributed" in English, distribute means "hand out" so you can think of the 10 as being "handed out" to each term inside the parens. (of course you have to remember you multiply 10 times each term)
