All of these sets meet the requirements of the triangle inequality. The sum of any two numbers in the set is greater than the third one. (You really only need to check that the sum of the smallest two is greater than the largest.)
It can help to resolve the numbers that are only indicated as to value.
√13 ≈ 3.606
2√10 ≈ 6.325
_____
Your comparisons can be ...
2 + 3 = 5 > 3.606 . . . is a triangle
5 + 5 = 10 > 6.325 . . . . . . is a triangle
5 + 12 = 17 > 15 . . . . . . . . is a triangle
Answer:2/3
Step-by-step explanation:
3/9=1/3
1/3+1/3=2/3
D
You figure out the absolute value by determining how far the number is from the point 0 on a number line.
The domain of f(x) is x > -3.
Given that
Function; 
We have to determine
The domain of f(x).
According to the question
To determine the domain of the function following all the steps given below.
The domain is defined as the set, which is to be input in a function. Or, we can say input values that satisfy a function.
Function; 
Then,
The domain of the function,

The domain is x > -3,
Hence, the domain of f(x) is x > -3.

An inequality is solved by more than one value - usually an interval, or a union of intervals.
In this case, we have:

Add 14 to both sides:

Divide both sides by 12:
