-53b² is the correct answer. First you had to remove parenthesis first, and it gave us, $-26b^2-27b^2$ . And then add similar elements, and it gave us the answer is $-26b^2-27b^2=-53b^2$ , or -53b² is the right answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

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.
