Answer:

2x+4

Step-by-step explanation:

if you double the triangle, than the sides double as well meaning you use distributive property to multiply two to each integer.

The length of AD given a scale factor of 2 is 10 units.

Given that, Δ ABC was dilated from point A to get Δ ADE.

We need to find the length of AD given a scale factor of 2.

How do you find the scale factor?

The basic formula that is used for calculating the scale factor is the Scale factor = Dimension of the new shape ÷ Dimension of the original shape. In case, if the original figure is scaled up, the formula is written as, Scale factor = Larger figure dimensions ÷ Smaller figure dimensions.

Now, 2=(6x-8)/(x+2)

⇒6x-8=2(x+2)

⇒6x-8=2x+4

⇒4x=12

⇒x=3

Then, AD=6x-8=6×3-8=10 units.

Therefore, the length of AD given a scale factor of 2 is 10 units.
