Question

12 pls. Dis is due tomorrow I need helppp

Answer 1

Multiplying positive numbers always comes out positive, no matter how many there are.  So you can forget about the positive ones.

Every two negative numbers in a multiplication produce a positive.
Another way to say that is:  If the number of negative ones is EVEN,
the answer is positive, and if it's ODD, the answer is negative.

That monster product of eight numbers in problem #12 will be negative,
because there are an odd amount of negative factors in it.
