Answer:
Second Option: 
Step-by-step explanation:
A fraction means to divide.

Therefore,

It would be a right angle because all the angles are less than 90 degrees
<span>3(2x+4y-2z)+7(x+y-4z) =
3*2x + 3*4y - 3*2z + 7x + 7y - 7*4z =
6x + 12y - 6z + 7x + 7y - 28z =
(6+7)x + (12+7)y + (-6-28)z =
13x + 19y + (-34)z =
13x + 19y -34z;
