Answer:

y - 9 = 5(x - 3)

Step-by-step explanation:

Here the point (h, k) is (3, 9), and the slope m is 5. Substituting these values into the point-slope formula y - k = m(x - h), we get:

y - 9 = 5(x - 3)

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.
