(12x8)*8
The GCF of 24 and 64 is 8. You use the distributive property to show another way to write the sum. 8(3 + 8)
It is not the distributive property. The statement in the question is simply FALSE.
18
8*31 = 8*(30 + 1) which, using the distributive property, is= 8*30 + 8*1 = 240 + 8 = 248
12
8*3.5 = 8*(3 + 0.5) which, applying the distributive property, = 8*3 + 8*0.5 = 24 + 4 = 28
8*37 = 8*(30+7) = 8*30 + 8*7 [that is using the distributive property] = 240 + 56 = 296
8 + 46 = 54.
The distributive property is a red herring for this question: you do not need it! The distributive property is applicable when you have two binary operations - multiplication and addition, for example. This question has nothing of the sort. Perhaps you meant some other property.
4 x 18 = (4 x 10) + (4 x 8)
8(3 + 8)
9*8 = 72. You do not need the distributive property for such a basic multiplication.
