To find perimeter, all you need to do is add each side of the shape together. In this case you have a quadrilateral. Since you did not attach a picture of the quadrilateral, I cannot give you the exact answer that you are looking for. But, I do know that you will have 4 numbers. Simply add them up and the sum will be your perimeter.

Step-by-step explanation:
41 plus 42 plus 43 = 126.
Distribute to each
(-4)(-6+4v+2u)=-4(-6)-4(4v)-4(2u)=24-16v-8u
