Question

In the figure below, n is a whole number. What is the smallest possible value for n? A.)1 B.)7 C.)8 D.)14

Answer 1

well, since the sum of any two sides of a triangle must be greater than the third side,

n+n>15
or, 2n>15
or, n>15/2
or, n>7.5

Now what do you think?

Answer 2

So maybe the smallest number it could be is 7?

Answer 3

Nope.
n must be greater than 7.5!!
now within that constraint, you've to see the smallest possible value in the options that could satisfy n

Answer 4

Oh, I am sorry, then the lowest is 8?

Answer 5

Yes! Right-o!!

Answer 6

Thanks! :)
