Question

1 (4 x 12) + (4 x 8) 2 4 x (12 - 8) 3 (4 x 12) - ( 4 x 8) 4 4 x (12 + 8)

Which expression shows 4 times the difference between 12 and 8.

Answer 1

Answer: 4 x (12 - 8)

Explanation:

the word difference really means exactly what it is saying. it is the quantity difference between two numbers. like, if someone would say, "what's the difference between 4 and 2?' then you would just subtract 2 from 4 to find the difference between the two numbers.

so, we now know that we are going to be subtracting 8 from 12.

plus, it tells us to show 4 times 12 - 8. that means that we will be multiplying (12 - 8) by 4.

so, our only viable option is 4 x (12 - 8).
