The answer is actually 17 and 18 and that choice isn’t listed here. You could solve this a few different ways, and one of those is by the guess and check method. Start by taking two numbers, say 15 and 16, and add them together. You would find the answer to be 31. You then realize that you need 4 more to make 35.

You can choose higher numbers, such as 16 and 17, until you find the pair that works. Choice 3 does not work because it doesn’t equal 35 and because the integers are not consecutive. Choice 2 doesn’t work because it only equals 13. #### dinkinsk

The answer is 1.2 x 10^8.
​When you calculate 52,000,000 by 24, you get 1,248,000,000 and because ofthe rule of scientific notation, you get 1.2 x 10^. Now, if you count from the right, there are six 0's and the digits 2, 4, and 8. So you can count 9 digits from the right before you can get to where the decimal point is. Therefore it is 1.2 x 10^8.

​ The rule of scientific notation: you can only have a one digit number before the decimal point. In this case it is 1 (from 1.2). You can't have 10 or 0 in this spot and are reserved for digits 1-9. #### hlengal
