Answer:
Step-by-step explanation:
If x=2, 2x^3-2x^2+3x-2 ≠ 0, so (x-2) is not a factor.
Answer: -30, -10, 15, 20
Step-by-step explanation:
Answer:
EF = 31
Step-by-step explanation:
Note that in both line segments (EG & FG), they both have point G in them. This means that point G is the shared point and the mid-point. Add the two line segments together to get the full segment.
EG + FG = EF
19 + 12 = 31
31 is your answer

Answer:
The required result is proved with the help of angle bisector theorem.
Step-by-step explanation:
Given △ABD and △CBD, AE and CE are the angle bisectors. we have to prove that 
Angle bisector theorem states that an angle bisector of an angle of a Δ divides the opposite side in two segments that are proportional to the other two sides of triangle.
In ΔADB, AE is the angle bisector
∴ the ratio of the length of side DE to length BE is equal to the ratio of the line segment AD to the line segment AB.
→ (1)
In ΔDCB, CE is the angle bisector
∴ the ratio of the length of side DE to length BE is equal to the ratio of the line segment CD to the line segment CB.
→ (2)
From equation (1) and (2), we get
Hence Proved.
Answer:
x=55 degrees
Step-by-step explanation:
Angle X + 125 degrees is 180 degrees. 180 minus 125 is 55.
