A four day old worm has 10 isoceles right triangles. A ten day old worm has
24 isoceles right triangles. A 63 day old worm from Trianglia has 128
isoceles right triangles. EXTRA: The worm would be 15 days old.
I found out that a 4 day old worm from Trianglia would have 10 isoceles right
triangles. I found this out because a 1 day old had 4 triangles, a 2 day old
had 6, a 3 day old had 8, so you would just follow the pattern and add 2. We
found out that a 10 day old would have 24 squares. First, we doubled 4 and
came up with 8 day old would be 20 squares. So if they grow 2 squares each
day that would be 4 triangles. So, 20+4=24 triangles and 8+2=10 days. A 63
day old worm from Trianglia would have 128 squares because 63x2+2=12

My final score is #1 4 days old. #2 20 triangles. #3 126 triangles.
For the first problem I added 8 and 2 and got 10 triangles for a 4
day old worm. For the second problem I multiplied 10 and 2 and got
20 triangles for a 10 day old worm. For the third problem, I
multiplied 63 and 2 and got 126 triangles for a 63 day old worm.
For the EXTRA I got a 30 day old worm by dividing 60 and 2 and
got thirty.

You will need 10 triangles for four days, 22 triangles for 10 days
and 128 triangles for 63 days. Extra: A worm made up of 60 triangles
would be 29 days old. Super Extra: The rule that uses a worm's age
(in number of days) to find out how many triangles it is made of is
x multiplied by 2 + 2. x --> age of worm
I started out by trying to solve the super extra which would help me
find the right way to solve the other questions. I started at day 1.
There are 4 triangles that made up that worm on day 1. 1+3 is 4. So
then i looked at day two, but 2+3 does not equal 6 which is the
number of triangles the worm was made up of. then i went to
multiplication. I started at day one again. 1x4 equals four. But
then i went to day two and 2x4 does not equal 6. Then i tried a
mixture of multiplication and addition. I took day one and started
to go up the number line. I couldn't do 1x1+1 because that only
equals 2. So then i did 1x2+2 and that equaled 4, which is the
number of triangles for that day. Then i multiplied and added 2 to
days 2 and 3 and it worked out. So then i got the answers for the
first three questions and the super extra. Then for the extra I
started at 10 days which was 22 triangles and I kept going up until
i got to 60 triangles.

The answer is x2+2.
We figured out the answer that is x2+2 because the example worms you
take the number of triangles by multipling the number x2 to the
day. Also you do +2 to the triangles.

A four day worm has 10 triangles,a 10 day worm 22 triangles,and a 63
day worm 78 triangles
I saw that each day older to a worm added two triangles so when I was
adding days I also added triangles.So four days makes 10
triangles,ten days 22 triangles,and 63 days 78 triangles.

4th one 10, 10th one 22, 63rd 128
I knew that the number of the worm was the number of the squares,and that
each square had 2 triangles in it. I also knew that there were 1 triangle on
each side of the worm.

A four year old worm is 10 triangles.A ten year old worm is 22
triangles.A 60 yeae old worm is 128 triangles.
First I drew a four year old worm and it had ten triangles.Next I
drew a ten year old worm and it was 22 triangles.Then I drew a
63 year old worm and it was 128 triangles.
For the extra a 29 year old worm hs 60 triangles.
For the super extra I found out thatyou add two and then add the
two together.
