Which are skew lines? Check all that apply. •A and B
•C and B
• B and E
• E and C
• A and E
• A and C

C and B; A and C; E and C;

Step-by-step explanation:

Skew Lines are lines that do not intersect and are not parallel. Skew lines must be in 2 different planes because in 1 plane 2 lines either intersect or are parallel. Assuming that a,b, and e are on the plane in front and c is on the plane in the back we can say that A and B, B and E, and A and E can not be skew lines because they lie on the same plane. This leaves C and B, E and C, and A and C.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
