Answer:

8N - 4 border tiles.

Step-by-step explanation:

There are 4 border tiles in each corner and between  the tiles there are N-2 tiles along the 4 sides.

So the number of border tiles

= 4+ 4(N - 2)

= 4 + 4N - 8

= 8N - 4.

Select the term that best describes the statement: The glass is not always half full. a. conjunction
vlada-n [284]

Answer:

c. negation

Step-by-step explanation:

A conjunction is two statements joined by "and"; that does not fit this statement, so it is not a conjunction.

A disjunction is two statements joined by "or"; that does not fit this statement, so it is not a disjunction.

A conditional is an "if-then" statement; that does not fit this statement, so it is not a conditional.

This is a negation; the word "not" negates "the glass is always half full."
