Two quadrilateral rectangles:
1. 6x5= 30
2. 5x10= 50
Two right triangles:
1. 10x6/2= 30
2. 10x6/2= 30
Then you add them all up:
30+50+30+30= 140 sq. units
It’s neither positive nor negative it’s the orgin i think
Answer: 
(x) = 3 - 5x
Step-by-step explanation:

-8 = 64 + 8n
-64 -64 subtract 64 on both sides, 64's cancel out on the right.
______________
-72 = 8n
___ ___ divide 8 on both sides, 8's cancel out from the right.
