Answer:

4

Step-by-step explanation:

The solid triangle dilated to become the dashed triangle.

Compare two corresponding sides. For example, the vertical side of the solid triangle measures 3 units. The vertical side of the dashed triangle measures 12 units. 12/3 = 4. The dilation is 4. The scale factor is 4.

Answer:

Scale factor: 4

Step-by-step explanation:

Let m be scale factor.

We have been given two triangles such that dashed triangle is image of the pre-image solid triangle.

First of all, we will find length of bases of both triangles by counting the units.

Base of pre-image: 2 units.

Base of image: [tex]3-(-5)=3+5=8[/tex] units.

We know that after multiplying a side of pre-image by scale factor, we get image.

[tex]2\cdot m=8[/tex]

[tex]\frac{2\cdot m}{2}=\frac{8}{2}[/tex]

[tex]m=4[/tex]

Therefore, the scale factor for given diagram is 4.
