Geometry problem in the picture, The polygons shown are similar find the values of X and Y

x = 14

y = 40

Step-by-step explanation:

if the polygons are similar then we can use the proportional values to find x and y:

20/45 = (2x-8)/(5x-25) cross multiply expressions

100x - 500 = 90x - 360 export like terms to the same side of the equation

100x - 90x = 500 - 360

10x = 140 divide both sides by 10

x = 14

since the polygons are similar 3y + 8 = 128 subtract 8 from both sides

3y = 120 divide both sides by 3

y = 40

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
