Answer» Step-by-step explanation: . If 15 integers are negative then PRODUCT of 15 integers is negative because it is ODD and the remaining are 3 POSITIVE numbers therefore there product will be positive and positive × negative is negative. Since out of EIGHTEEN integers 9 of them are negative, which is odd number. Hence, sign of product will be negative (-). Since all are negative, which is even number. Hence sign of product will be positive (+) If a negative number is multiplied even number of times product is always positive. 3) Since, 9 are positive and thus 9 will be negative because total no. of integers are 18 hope it helps you mark me as the BRAINLIEST ✌️ |
