Answer:
4x^2-16x
Step-by-step explanation:
4x(x-4)
4x(x)-4x(4)
4x^2-16x
Yes , maybe the word each represents a different operation , but I'm pretty sure that sometimes (each) represents division.

Answer: The corrected statement is A - B = -B + A.
Step-by-step explanation: Given that the subtraction of a matrix B may be considered as the addition of the matrix (-1)B.
We are given to check whether the commutative law of addition permit us to state that A - B = B - A.
If not, We are to correct the statement.
If the subtraction A - B is considered a the addition A + (-B), then the commutative law should be stated as follows :
A + (-B) = (-B) + A.
That is, A - B = -B + A.
Thus, the corrected statement is A - B = -B + A, not B - A.
