4 |m - n|
-if m = -7 and n= 2

9

Step-by-step explanation:

I m - n I = I -7 - 2 I

{ Both are negative integers. So, add and result will have the negative sign}

            = I -9 I

            = 9

-36

Step-by-step explanation:

We have the equation 4 lm - nl , along with the values, m is equal to -7 and n is equal to 2.

To solve, we need to only substitute the values of each variable into the original equation :

4 |-7 - 2|

First solve the equation within the absolute value, any value that comes out of those brackets become positive :

|-7 - 2|

|-9|

4|-9|

4(-9)

Now multiply to get our

4(-9)

-36

the 4th choice is the correct one
