9(2a)²+2 pasagot naman with solving lang thanks

Using elimination, what is -4x+2y=-12 4x+8y=-24

The figure shows triangle def and line segment bc, which is parallel to ef: triangle def has a point b on side de and point c on side df. the line bc is parallel to the line ef. part a: is triangle def similar to triangle dbc? explain using what you know about triangle similarity. part b: which line segment on triangle dbc corresponds to line segment ef? explain your answer. part c: which angle on triangle dbc corresponds to angle f? explain your answer. asap

Is of - 4x + 2? a. 3 b. 4 c. 6 d. 5
