Answer:
(mn)(-3) = -3mn ....
Step-by-step explanation:
We have given the expression:
(mn)(x)
The value of x is given, which is = -3
Now we just have to substitute the value of x in the given expression.
The expression is:
(mn)(x)
If we substitute the value x = -3 in the expression it becomes,
(mn)(-3)
Now by multiplying both the brackets we get:
(mn)(-3) = -3mn ....
