Adam has a greater rate of change, as seen by the larger slope. This means Adam is traveling faster than Katia.
Answer:
Let l be length and w be width.
First equation:
l = 2w-4
Second equation:
perimeter = 40 units
Perimeter of a rectangle: 2(l+w)
2(2w-4+w)=40
2(3w-4)=40
6w-8=40
6w=40+8
6w=48
w=48/6
w=8
Therefore the width=8;
length= 2w-4 = 2(8)-4 = 16-4 = 12
perimeter = 40 units
