$Q+S-T=7m+3n+n+5-(-m-3n+8)\\
Q+S-T=7m+4n+5+m+3n-8\\
Q+S-T=8m+7n-3$

*A triangle has sides 42, 4x, and 2x−6. What is the possible range of x?

scoray [572]

Answer:

<h2>The Possible range for x is : ]8 , 18[</h2>

Step-by-step explanation:

To can draw this triangle if:

4x - (2x - 6) < 42 < 4x + (2x - 6)

solve inequality 1 :

4x - (2x - 6) < 42 ⇔ 2x + 6 < 42 ⇔ 2x < 36 ⇔ x < 18 (1)

Solve inequality 2 :

42 < 4x + (2x - 6) ⇔ 42 < 6x - 6 ⇔ 48 < 6x ⇔ 8 < x (2)

from (1) and (2) we deduce that : 8 < x < 18
