Hello! I know that this is right I just want to know where that extra (x-6) came from. The equation went from y = (((6*2)/(x-6))+2)(x-6) all divided by 2 into being ((6*2+(x-6)2)/(x-6))(x-6) all divided by 2.

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

look at the picture.

1.

ef : ab = 2 : 3

gf : cb = 2 : 3

gh : cd = 2 : 3

he : da = 2 : 3

2.

∠a ≅ ∠e

∠b ≅ ∠f

∠c ≅ ∠g

∠d ≅ ∠h

3.

use pythagorean theorem:

the length of the abcd trapezoid sides:

|ab| = 3 cm

|bc| = 10 cm

|cd| = 3(3) cm = 9 cm

|da| = 8 cm

the perimeter of abcd = 3 + 10 + 9 + 8 = 30 cm

the ratio of perimeters of the tarapezoids is equal 2 : 3.

substitute:

      cross multiply

      divide both sides by 3
