To find side b, you have to find the ratio between both triangles.

TD/JK=9/5 or 1.8

A common error here is that you multiply side DP by the ratio.

What you actually have to do here is divide side DP by the ratio

DP=6, so 6/1.8

6/1.8= \(3.\overline3\)

T=Triangle, D=Diamond, S=Square, and C=Clover

T+T+T+T+T=D 

T can't be larger than 1 because D would be larger than 9.

So this means 1+1+1+1+1=5, which D=5

1+S+S=5

1+2S=5

2S=4

S=2

Square is equal to 2

S+D=C = 2+5=7, so C is equal to 7

T=1, D=5, S=2, C=7

I know CubeyThePenguin got a different answer, so I'm not sure if Cubey's or mine is correct :)

Sooo... basically 5 feet * 4 feet and 8 inches?

In feet it would be 23 feet 4 inches?

In inches it would be 280 inches?

Didn't I just help you with these?

Yes, A is for 14. and B is for 15. :)

This is for problem 2:

a. Plug in some values for \(f(x)=6x-4\)

This matches to 19.

b. If you are wondering how to solve this function, here's how:

Since you already know what f(1) is, you can start solving for f(2)!

\(f(2)=6 * f(2-1)= 6*f(1)= 6*2= 12\)

By doing this two more times, you can see this matches to 16.

c. Plug in some values for

You see this function matches to 18.

By this you can match d. to 17.

Matches:

16 ---> b.

17---> d.

18---> c.

19---> a.

This is for problem 1:

An easy way to determine if a sequence is geometric or arithmetic is by seeing if it is multiplied or divided by a number (geometric) or added or subtracted by a number (arithmetic). 

A. The numbers in the sequence are divided by a number, the number being 2. This means it is geometric!

B. The numbers in the sequence have a number added to them, the number being 4. This means it is arithmetic!

Well neither is a calculator. Me giving answers is the same as looking for answer on a calculator, right? Not trying to be mean, but I don't think it's a good idea to write an entire article on webcalc. Long division isn't hard, I think. But I'm not really supposed to teach them something that already has many articles about it and/or their teacher taught them. Can they not ask their teacher? I'll give a short summary of long division then. However, a calculator, like CPhill said, is a good tool for double-checking! :)

Long division is division but longer. Here are the steps for it:

1. Divide the tens column dividend by the divisor.

2. Multiply the divisor by the quotient in the tens place column.

3. Subtract the product from the divisor.

4. Bring down the dividend in the ones column and repeat.

Hope this somewhat helps! :))))

1. \(\frac{5}{32}=0.15625\)

2. \(6 \frac{1}{16}=\frac{97}{16}=6.0625\)

3. \(8 \frac{21}{40}=\frac{341}{40}=8.525\)

4. \(8 \frac{43}{80}=\frac{1003}{80}=12.5375\)

5. \(9 \frac{9}{32}=\frac{297}{32}=9.28125\)

Not sure if this helps.
