The middle section is n(n+1)

The top row is n+2

The bottom row is 2n+1

So the rule for the total number of tiles will be the sum of the above rules...

s(n)=n(n+1)+n+2+2n+1

s(n)=n^2+n+n+2+2n+1

s(n)=n^2+4n+3

Is the simplified form of 2 v3 · 2 v6 rational?
tatuchka [14]

Answer:

No

Step-by-step explanation:

2√3 × 2√6

= 4√18

= 4√9*2

= 4( 2√2)

= 8√2

Just multiply the numbers under the radical together.  √3 × √6 = √18.  √18 can be written as √9*2, or 3√3.

√2 is irrational, so the answer will be irrational
