Step-by-step explanation:

Hey there!

A. 3x5 is 15! However since one of the number is a negetive, we must add a negetive sign to the 15, making it -15!

Remember this: A negetive number times a negetive number is a posititve number, but a negetive number times a positive number is a negetive!

B. 5+-5 is equal to 0, so 3x0 is 0!

C. No matter which way you mutliply it, whether it's -5x3 or 3x-5, the answer will always be -15! (-5)x(3+-3) is: 3+ -3 is 0, so -5 times 0 is the same thing as 5x0, which is still 0!

D. Like I said before, a negetive times a negetive is a positive, so -3x-5 is the same as saying 3x5, which is 15!

I hope this explanation helps you! Please mark me Brainliest!
