find two numbers which have a difference of 7 and a product that is a minimum
how do you solve this ? what does it mean when it says a product that is a minimum?

Dunno. Maybe she means two numbers with the smallest possible product, in which case we would find the minimum of the function x(x+7). Expanding this, f(x)=x²+7x, and f'(x)=2x+7, thus the minimum value occurs at x=-3.5. The two numbers are then -3.5 and 3.5, and their product is -12.25 .

they want the two numbers when that when multiplied will be the smallest of all the possible solutions
2 numbers with a difference of 7 .... 10 and 17 .... 170 when multiplied
1 and 8 ... 8 when multiplied
now depending on what set of numbers you can use
0 and 7 ... 0 when multiplied
not sure if they want you to use 0 as a possible number or not.

7 and 0
7-0=7
7*0=0
