A scale factor of (A. 0.125 or B. 8) was applied to the first triangle to the get the resulting image.

This scale factor is an enlargement? or a reduction?

2.4 รท 0.3 = 8
Scale factor = 8
8 = positive integer
Therefore, it is an enlargement

Answer:

Part A) The scale factor is equal to
8

Part B) Is an enlargement

Explanation:

we know that

The scale factor is equal to divide the corresponding side of the resulting triangle by the corresponding side of the first triangle

Let

z----> the scale factor

x------> the corresponding side of the resulting triangle

y-----> the corresponding side of the first triangle

so


z=(x)/(y)

we have


x=2.4\ units


y=0.3\ units

substitute


z=(2.4)/(0.3)=8

Remember that

If the scale factor is greater than one------> is an enlargement

If the scale factor is less than one------> is a reduction

In this problem


8> 1 -------> is an enlargement
