Katrina is asked to simplify the expression -3a-4b-2(5a-7b) @ultrilliam @vocaloid @zarkam21

7 months agostart by distributing this part 2(5a-7b) = ?

7 months ago(5a - 7b)2?

7 months agoA(B-C) = A*B - A*C following the same logic 2(5a-7b) = ?

7 months agolet's try and dissect A(B-C) = A*B - A*C to see what it means we take the number on the outside, A, and multiply it by the first number on the inside to get A*B then we take the number on the outside, A, and multiply it by the second number on the inside, to get A*C then the solution becomes A*B - A*C

7 months agoapplying this logic to 2(5a-7b) = ? we get 2*5a - 2*7b = ?

7 months agowhere not supposed 2 b solving this were supposed to figure out which property

7 months agooh in that case she would start by ~distributing~ 2(5a-7b) so which property is this?

7 months ago-3a-4b-2(5a-7b)=-3a-4b-10a+14b

7 months agoyes, so she ~distributed~ -2(5a-7b), what property is this?

7 months agowitch property is that ?

7 months ago~distributed~

7 months ago= distributive property

7 months agothe associative property

7 months ago?

7 months agoemphasis on the word ""distributed"" = "distributive property"
