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  .

J + i + t = 36
j = 2i
t = j + 1.....t = 2i + 1

5i = 36 - 1
5i = 35
i = 35/5
i = 7 <=== Inez downloaded 7 songs

j = 2i = 2(7) = 14 <==Jane downloaded 14 songs
