Answer:
Options (1) and (2)
Step-by-step explanation:
In 3-dimensional geometry,
Skew lines are lines which do not intersect and are not parallel.
From the given triangular prism,
Option (1). RS and TU
Sides RS and TU are neither parallel nor intersect each other.
Therefore, these lines are skew lines.
Option (2).QR and SV
Since QR and SV neither intersect nor parallel,
These lines are the skew lines.
Option (3) RS and RU
Since RS and RU intersect at R therefore, they are not the skew lines.
Option (4).RS and UV
Since RS and UV are the parallel lines therefore, they are not the skew lines .

Answer:
112x-420
Step-by-step explanation:
(5x + 9) (8x - 30)
distribute 5x into (8x-30)
then same with 9 into (8x-30)
then combine like terms and u will get da answer
hope this helps with da pic dat i attach
