Delicious77 [7]

Answer:

Proof below

Step-by-step explanation:

Let's assume a is a type 1 integer. By definition, it means we can find an integer n such that

a=3n+1

We need to prove $a^2$ is a type 1 integer

Expanding

$a^2=(3n+1)^2=9n^2+6n+1$

If $a^2$ is a type 1 integer, then we should be able to find an integer m such as

$a^2=3m+1$

Equating

$a^2=3m+1=9n^2+6n+1$

solving for m

$m=3n^2+2n$

Since we know n is an integer, then the expression of m gives an integer also. Having found the required integer m, the assumption is proven

Darya [45]

Answer:

If there's 10 cookies in the jar, and if 2 are peanut butter, the fraction for peanut butter cookies is 1/5, simplified.

Step-by-step explanation:

Given:

10 Cookies Total
3 are Oreo cookies
2 are peanut butter cookies
4 are chocolate chip cookies
1 is a sugar cookie

Bolded text represents what we'll be focusing on.

2 of the cookies are peanut butter, and there's 10 cookies total.

As a fraction, the peanut butter cookies are represented as:

2/10.

2/10 represents 2 peanut butter cookies out of 10 cookies altogether.

Simplify:

2/10 can be simplified by dividing both numerator and denominator by 2:

Quotient: 1/5.

1/5 is your answer.
