A number is less than 4 units from 0
-4<x<4
Sqrt242 can't be simplified anymore. It doesn't contain any perfect squares factors. For instance,

This can be simplified because

And 25 is a perfect square, and square root of 25 is 5. The simplified version for this would be 5 sqrt (6). For your question, sqrt 242 can't be simplified anymore, its most simplified version is its current state.
it would be the third answer choice, when doing this you always make sure that there is multiplication or division you do those first going left to right, even if there is addition first, you still would do either multiplication or division first.

Answer:
The Proof for
△ABD ≅ △CBD is below
Step-by-step explanation:
Given:


AD = CD .........BD bisect AC
To Prove:
△ABD ≅ △CBD
Proof:
In ΔABD and ΔCBD
BD ≅ BD ....……….{Reflexive Property}
∠ADB ≅ ∠CDB …………..{Measure of each angle is 90°(
)}
AD ≅ CD ....……….{
}
ΔABD ≅ ΔCBD .......….{By Side-Angle-Side Congruence test} ...Proved
