It is not the distributive property. The statement in the question is simply FALSE.
8*31 = 8*(30 + 1) which, using the distributive property, is= 8*30 + 8*1 = 240 + 8 = 248

8*3.5 = 8*(3 + 0.5) which, applying the distributive property, = 8*3 + 8*0.5 = 24 + 4 = 28
4 x 18 = (4 x 10) + (4 x 8)
8(3 + 8)
8(3 + 4)
8(7 + 4)
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.
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 states that 5*(8+3) = 5*8 + 5*3

To solve 8x9 using the distributive property, you can break down 9 into 5 and 4, as 8x5 + 8x4. This simplifies to 40 + 32, which equals 72. By applying the distributive property, you are essentially distributing the 8 to both the 5 and the 4 before adding the products together.
8*3.5 = 8*(3 + 0.5) which, applying the distributive property, = 8*3 + 8*0.5 = 24 + 4 = 28
