Asquare has sides of 5x + 2y on an equilateral triangle has a side length of 3x - 1. what is the difference of the perimeter of the square and that of the triangle?

tried on you are knowing that we can't leave the picture in the graph ok no problem now you need to send it in the question group

yeah i know the problem you need. i am taking it right now. the answer is step 3

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
