x(x+4)+4(x+4)>0
(x+4)(x+4)^2>0
this is true cause (X+4)^2 >0 cause X+4>0

Answer:
<DEF = 107
Step-by-step explanation:
The way to best solve this problem is by starting with angle F. Remember that all angles in a straight line must add up to 180. So by subtracting 135 from 180 we get 45 for angle F.
180 - 135 = 45
After that, we can figure out the measure of <DEF. All the angles of a triangle must add up to 180. So:
180 - 28 - 45 = 107
Making the answer 107 for the measure of <DEF
The answer is 3ax -by + c hope this helps
