Answer:

x=18 and y=34

Step-by-step explanation:

y = 2x - 2; x = 18 (rewrite this)

x=18;y=2x−2

solve for x( x=18)

substitute 18 for any x in y=2x-2

y=2x-2

y=(2)(18)-2

y=34(simplify both sides of the equation)

sorry for the lengthy explanation i hope this helps, i hope you have a great day :) !!

Gemiola [76]

Answer:

Perimeter of polygon B = 80 units

Step-by-step explanation:

Since both polygons are similar, their corresponding sides and perimeters are proportional. Knowing this we can setup a proportion to find the perimeter of polygon B.

$\frac{side-polygonA}{side-polygonB} =\frac{perimeter-polygonA}{perimeter-polygonB}$

Let $x$ be the perimeter of polygon B. We know from our problem that the side of polygon A is 24, the side of polygon B is 15, and the perimeter of polygon A is 128.
