It would be 21 as a percent and 0.21 as a decimal
To solve this you have to take the numbers and subtract them and that will give you the pattern.
Ex. For #9 do 26-19 then to check and see if that helps the pattern do 36-26
Hope this helps:)
No, it's not possible for the sides of a triangle to have those lengths.
According to the triangle inequality theorem, the sum of any two sides of the triangle has to be bigger than the last side. Let's test this.

This inequality satisfies the triangle inequality theorem.

This also satisfies the theorem.

Uh oh. This does not satisfy the triangle inequality theorem. Thus, it is not possible for a triangle to have these side lengths.
