You have to set up to equations
EQ 1: x-2=2 EQ 2: x+2=2
Solve for x and see which value fits the conditions, in this case 4
Answer:
One
Step-by-step explanation:
First, we need to check a triangle with these sides <em>is</em> possible. Since 4 plus 5 is 9, and 9 is less than 10, we can make a triangle with these sides.
To answer the question, we can only make one unique triangle. Why? They give us three lengths and a triangle has three sides.
<em>However</em>, if they are counting a triangle in different positions the answer will be greater. Since it would just be the same triangle, I am going with the answer of only one.

A rate shows how much larger or smaller one box is to the other box.
F(x)=1/(x-3)^3
The denominator can't be equal to zero (we can't divide by zero), then:
(x-3)^3 different 0
cubic root both sides:
cubic root [ (x-3)^3 ] different cubic root (0)
x-3 different 0
Adding 3 both sides:
x-3+3 different 0+3
x different 3
