The answer would be 208 if you find the area of each quadrilateral and add them together.
54 rounded to the nearest 10 would be 50 because 54 is closer to 50 than 60.
So, the answer is 50.
Hope it helps
Answer:
Firstly you need to put the equation in form of. y =ax+b
Let us do it
We have
2x-2y=18
-2y=18-2x
-y=(18) /2 - (2x)/2
-y =9-x
Mutiply by - to remove it beside y
Y=-9+x
Which is y=x-9
Slope =a=1
Yintercept=b=-9
