Answer:
Last choice
Step-by-step explanation:
To say it simply if products are in negative or not, we can tell by:-
- Looking at negative symbols
- Then count how many negative signs are there.
- If there are even-number signs (2 negative signs, 4 negative signs, etc.) then the product is positive.
- If there are odd-number negative signs (a negative sign, 3 negative signs, 5 negative signs, etc.) then the product is negative.
The only choice that has odd-number negative signs is last choice — othere have 2 or 4 negative signs.
Additionally, keep in mind that:-
- positive • positive = positive
- positive • negative = negative
- negative • negative = positive
- same signs multiply each others = same sign
- opposite signs multiply each others = negative (For plus and minus)
