42
The Abelian or commutative property of addition of integers, rationals, reals or complex numbers.
Its 91
7*46 = 7*(40 + 6) = 7*40 + 7*6 = 280 + 42 = 322
You multiply the outside number touching the parenthesis by the numbers inside. Ex: 6(x - 5) = 42 6x - 30 = 42 6x = 72 x = 12
Individual numbers do not have the distributive property - mathematical operations do.
An unnecessary one. 42 + 96 = 138
The distributive property states that when you have a problem, say 3(42-36) then you distribute the multiply by 3 to the 42 and -36 to get 126-108 which can be easier to solve some times. Also when you simplify problems with variables, you can substitute 5n+15 to 5(n+3).-------a(b+c) = ab+ac
(2 x 14) + (3 x 14) = 5 x 14 = 70
42
18 + 24 = (3 x 6) + (4 x 6) = 7 x 6 = 42
The Abelian or commutative property of addition of integers, rationals, reals or complex numbers.
If 15 + 3x = 42, then x = 9
Its 91
7*46 = 7*(40 + 6) = 7*40 + 7*6 = 280 + 42 = 322
distributive property, and substitution property. EX: 42 x 20 = (40 + 2) x 20 = (40 x 20) + (2 x 20)
You multiply the outside number touching the parenthesis by the numbers inside. Ex: 6(x - 5) = 42 6x - 30 = 42 6x = 72 x = 12
