Answer:
3(8+2a)
Step-by-step explanation:
You just want to simplify the equations to see if they equal 6a+24, which in this case 3(8+2a) does. The other two equal something else, hopefully this helps :)

Answer:
c
Step-by-step explanation:
Triangle ABC is isosceles (even tho' it doesn't look so).
m<BDE = m<BED because of that.
Thus, 66 degrees + 2 m<BDE = 180 degrees, and
2 m<BDE = 114 degrees. Thus, m<BDE = 57 degrees.
