Question

PLEASE ONLY ANSWER WITH A PROPER ANSWER FOR EACH ONE...NOT JUST FOR POINTS-Thank you so muchhhh

Answer 1

Answer:

$x > \frac{1}{2}$

Step-by-step explanation:

For the first one, in any triangle, we have the sum of two sides is greater than the third side. Hence, we have 3 inequalities: $4x+3>2x+1, 5x+1>x+3, 3x+4>3x$, which give us $x>-1, x>\frac{1}{2},4>0$. We conclude that $x>\frac{1}{2}$.

For the second question, we have $AB$, and similarly we can show that $AC, BC$. Hence, $AB+BC+AC$.

The third question is not very clear.
