Answer:

-30

Step-by-step explanation:

I'm assuming the equation is $4m-n$ . If it is not please tell me.

If we know the values of m and n, we can just substitute inside the expression.

$4(-7) - 2\\\\-28 - 2\\\\-30$

Hope this helped!

What is the area of a parallelogram whose vertices are A(−1, 12) , B(13, 12) , C(2, −5) , and D(−12, −5) ?

<span>238 square units. The area of a parallelogram is the base multiplied by the height. You can use any of its four sides as the base, so pick the one that is easiest to deal with. Examining the parallelogram, you'll notice that line segments AB and CD are both parallel to the x axis which makes it extremely easy to calculate the height which is 12 - (-5) = 17. The length of AB is 13 - (-1) = 14. So the area of the parallelogram is 14 * 17 = 238</span>

Answer:

Nope

The absolute value of a number or an expression is always positive or zero. It cannot be negative. With absolute value, we are only interested in how far a number is from zero, not the direction.

Step-by-step explanation:

The absolute value of a number means the distance from 0. ... You cannot have negative distance, so it has to be positive.

How can you use absolute value to represent a negative number?

EX:

Subtract one number from the other and give the result the sign of the number that has the greater absolute value. 2 – 9 = -7 because the difference between 9 and 2 is 7 and the -9 has the larger absolute value making the result negative.

(SORRY) IF THIS IS WRONG THIS IS WHAT THE INTERNET GAVE TO ME <3 anyways i hope this kinda help you understand
