Point D is the centroid of triangle ABC. AG is perpendicular to CB and GB = 8, AE = 5.75, AD = 4 and AC = AB. Find AB. Numbers on photo - 5.75 and 4, 8.

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

faster, im not sure why but i know it is faster

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
