25 points! david did not notice the multiplication sign between two three-digit numbers and wrote one six-digit number, which is equal to seven times their product. find these numbers. and also: let's call three prime numbers "cool" if their product is five times greater than their sum. how many "cool" triples are there?

Step-by-step explanation:

I can only do the first one, and then only by brute force. If both numbers can be the same, then David would write 143143

143 * 143 = 20449

7 * 20449 = 143*143. It is the only answer that came up from 100 to 999.

If I get the second one, I'll put it in the comments. But I can only do it by brute force as well, if I can do it at all.

i'm not entirely sure

if you ask home depot or lowe's they might be able to you out
