Slope of AB = 1/3 and slope of BC = -3 so these 2 lines are perpendicular
The same is true for all the other adjjacent pairs of lines.
Oppoitse lines are also paralllel ( slope of AB = 1/3 and slope of DC = 1/3) and other pair are both of slope -3.
So Its C
Answer:
Is there a x somewhere or is that litteraly how the equation is?
If so, -7 multiplied by 2 is -14,
-1 times -7 is 7,
add it together and you get
-7=28,
you could add 7 to both sides or subtract 28 from both sides and you'll get either 0=35 or -35=0
which would make the solution false since both sides are not the same

Answer:
- 108
Step-by-step explanation:
Substitute s = - 3 into the expression
- 3 | 15 - (- 3) | + 2(- 3)³
= - 3 | 15 + 3 | + 2(- 27)
= - 3 | 18 | - 54
= - 3 × 18 - 54
= - 54 - 54
= - 108
