Step-by-step explanation:
I Think Its C
Let x be the length and y be the width of a rectangle.
Area = xy
When x and y are doubled
Length = 2x and Width = 2y
Area = 2x x 2y
Area = 4xy
-------------------------------------------------------------------------------------------------
Answer: When the dimension is doubled, the area is 4 times the original.
-------------------------------------------------------------------------------------------------
The answer I got was y=-12x+43.
Hope this helps!
Estimate 189 to the nearest tenth which would be 190. And then do the same for 643 which would be 640. 640-190= 450
