Draw a scaled copy of this polygon that has a perimeter of 30 units. what is the scale factor? explain how you know

The scale factor is 3.

Step-by-step explanation:

Since,

∵ If sides of a polygon are changed by a scale factor 'a' then its perimeter is also changed by the same scale factor,

By the given drawing,

The actual perimeter of the polygon = 10 unit,

Also, the scaled perimeter = 30 units ( given )

Hence,

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
