Prime numbers are numbers that can only be divided by 1 and itself. The first five prime numbers are 2, 3, 5, 7, 11, and so on.

Composite numbers are numbers that are divisible by integers other than 1 and itself. The first five composite numbers are 4, 6, 8, 9, 12

1 is not considered a prime number or a composite number.

Because 5+1=2+4=6, then we can make them subtract from each other and multiply it to the remaining numbers to get 0.

3*[(5+1)-(4+2)]=0

A=l*w

l=length

w=width

A=area

@Guest yeah that is a faster way I should've done that

Can you please rephrase that? I'm not sure what {1; 1, 2, 1, 2, 1, 2, 1, 2.........etc.}. Also, I think the mathy term you are trying to say is "repeating decimal", or "continued decimal".

We make 2 equations(x is the smaller number; y is the bigger number):

y-x=9

3x=2y

y-x=9

y=(3x)/2

(3x)/2-x=9 => (3x)/2-(2x)/2=9 => x/2=9 => x=18

y=(3*18)/2 => y=54/2 => y=27

Therefore, x and y are 18 and 27 respectively.

There are 2 3s, a 5, and 3 qs.

3*3=3^2

q*q*q=q^3

We get 3^2*5*q^3, so simplifying, we get 45q^3.

(4*10)(2*10)=40*20=800

Was this a joke or were you really stuck on this?

Yes, but it's not a cheat sheet. It is for when you are stuck you can ask for help.
