Answer:
![x = \frac{9}{2}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B9%7D%7B2%7D)
Step-by-step explanation:
x - 2 (x -
) = 2 (4 - x) + 10
x − 2 ×
=2(4−x)+10
x−(−x)=2(4−x)+10
x+x=2(4−x)+10
2x=2(4−x)+10
2x=8−2x+10
2x=−2x+18
2x+2x=18
4x=18
![x = \frac{18}{4}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B18%7D%7B4%7D)
![x = \frac{9}{2}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B9%7D%7B2%7D)
Answer:
6x²
Step-by-step explanation:
3x×2x=6...... then an x²
Therefore answer is 6x²
Answer:
18 units
Step-by-step explanation:
The centroid is located 1/3 the distance from the midpoint of a side to the opposite vertex. That means ...
CG = 2·DG = 6 + DG
Then
DG = 6 . . . . . . subtract DG from the above equation
Of course, ...
CD = CG +DG = 2·6 +6
CD = 18
