<span>Is the following definition of perpendicular reversible? If
yes, write it as a true biconditional.</span>
Two lines that intersect at right angles are perpendicular.
<span>A. The statement is not reversible. </span>
<span>B. Yes; if two lines intersect at right
angles, then they are perpendicular.
</span>
<span>C. Yes; if two lines are perpendicular, then they intersect at
right angles. </span>
<span>D. Yes; two lines
intersect at right angles if (and only if) they are perpendicular.</span>
Your Answer would be (D)

Answer:
(-∞ , -1) ∪ (4 , ∞)
Step-by-step explanation:
-1 > 3x + 2 or 3x + 2 > 14
-1> 3x + 2 or 3x + 2 > 14
-1 - 2 > 3x or 3x > 14 - 2
-3 > 3x or 3x > 12
-1 > x or x > 4
(-∞ , -1) ∪ (4 , ∞)
Hope it helps :)
