Δ ABC was dilated from point A to get Δ ADE. Find the length of AD given a scale factor of 2.

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.

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
