Answer:
A . -48
B . 50
C . 0
Explanation:
We are asked to multiply three different problems, so, let us look at A.
(-4)12 = -48
How?
Well, simple, you have to multiply 12 by 4 which is 48. Now since there is a negative, a positive multiplied by a negative always is a negative. 48 becomes -48.
Now B. :
(-5)(-10) = 50
How?
Well, do normal multiplication at first, 5 by 10 which is 50. Now, there are two negatives , so, a negative times another negative is always positive. So 50 stays as 50.
Now C . :
(-17)(0) = 0
How?
Well, any number multiplied by zero is zero. Therefore, your answer is zero
