Answer:
4
Step-by-step explanation:
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.
If you add 2 and 4, you will get 6. This is the right answer because the only answer that is incorrect is the 4th, it has to equal a minimum of 7, not 6.

Answer:        4x² -4
Step-by-step explanation:
First, evaluate the exponent you'll get,  + 4x² -5 then evaluate to get, 1+ 4x² -5. Next, subtract the numbers, 1 + 4x² -5 then to get, -4 +4x². Lastly, rearrange the terms,  -4 +4x² turns into, 4x² -4!

Answer:
x = 7.5
Step-by-step explanation:
Given that BE is parallel to CD and intersects the 2 other sides, then it divides the 2 sides in proportion, that is
 =
 =  , substitute values
, substitute values
 =
 =  ( cross- multiply )
 ( cross- multiply )
8x = 60 ( divide both sides by 8 )
x = 7.5
