⇒
⇒
⇒
In this , square compost with can have 1000 earthworms ! if side is 3 times longer i.e. New side = , So , new area will be :
⇒

Answer:
<u>In week 20, Seth will have 80 cards and Matt will have 60.</u>
Step-by-step explanation:
Let's find out the amount of cards that Math and Seth will have in week 20, using the information shown in the graph and table:
Amount of cards Seth has in week 20 = 20 * 4 = 80
The equation to find out the amount of cards, c, Seth has in week w:
c = 4w
Amount of cards Matt has in week 20 = 20 + (2 * 20) = 20 + 40 = 60
The equation to find out the amount of cards, c, Matt has in week w:
c = 20 + 2w
<u>In week 20, Seth will have 80 cards and Matt will have 60.</u>
