Answer:

Scale factor = ½

Step-by-step explanation:

The original image is the preimage = ∆ACB

The new image is the image = ∆DFE

The scale of factor of dilation = image/preimage = DF/AC

DF = 6 cm (given)

AC = 12 cm (given)

Plug in the values into the equation to find the scale factor of dilation:

Scale factor = 6/12

Scale factor = ½

Answer:

$12x^2+8x+25$

Step-by-step explanation:

Given

From Figure

Sides of Triangle

$8x^2 \\4x^2+15\\8x+10$

Now, using concept

Perimeter of triangle = Sum of the sides of triangle

So,

Perimeter of triangle = $8x^2+4x^2+15+8x+10$

Adding $8x^2$ and $4x^2$ , so,

Perimeter of triangle = $12x^2+15+8x+10$

This can be written as

Perimeter of triangle = $12x^2+15+8x+10$

Adding 15 and 10,

Perimeter of triangle = $12x^2+8x+25$

So, the correct choice is = $12x^2+8x+25$

Hope this helps.
