Which two line segments are skew?

a. lines de and ge
b. lines ei and gk
c. lines gk and dh
d. lines hi and df

Skew lines are two lines that do not intersect and are not parallel.

Consider all options:

A. Lines DE and GE intersect at point E, then they are not skew lines.

B. Lines EI and GK are parallel, then they are not skew lines.

C. Lines GK and DH are parallel, then they are not skew lines.

D. Lines HI and DF lie in two parallel planes IKJH and EGFD, respectively. Then these lines do not intersect. Lines HI and DF are not parallel, then these lines are skew lines.

correct choice is D

i think it would be 42cm

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
