So we know 3 x 3 = 9 right? Than 12 - 3 = 9 or 12 - 9 = 3!!! They both use the same numbers. Subtraction is the opposite of addition and allows us to check our answers.

Hope I Answered Your Question!!!

cluponka [151]

Answer:

$x-1$

Step-by-step explanation:

If a, b and c are the lengths of the triangle's sides, then

$a+b>c,\\ \\a+c>b,\\ \\b+c>a.$

Since

$a=2x+2,\\ \\b=x+3,\\ \\z=n,$

then

$2x+2+x+3>n\Rightarrow nx+3\Rightarrow n>1-x,\\ \\x+3+n>2x+2\Rightarrow n>x-1.$

Thus,

$x-1$
