Given:
Point G is the centroid of triangle ABC.
FG = x + 8 and AG = 6x - 4
To find:
The value of the variable x.
Solution:
Using rule of centroid:




Multiply by 3 on both sides, we get
⇒ 3(6x - 4) = 2(7x + 4)
⇒ 18x - 12 = 14x + 8
Subtract 14x from both sides.
⇒ 4x - 12 = 8
Add 12 on both sides.
⇒ 4x = 20
Divide by 4 on both sides.
⇒ x = 5
The value of x is 5.
The answer is y= 3x^2+9x-13

Let h represent Kate's height at birth. Then: 142 cm = 3h - 2 cm.
Combining like terms: 144 cm = 3h, and h = 48 cm.
Kate's height at birth was 48 cm.
