CAN SOMEONE PLEASE HELP OR EXPLAIN HOW TO DO IT ... 6. If ABC-ADEF and the scale factor from ABC TO A DEF is , what is the
length
of ED?

5

Step-by-step explanation:

One is given that the scale factor to get from triangle (ABC) to triangle (DEF) is (). This essentially means that one has to multiply the sides of (ABC) by () to get the corresponding side in the triangle (DEF).

As one can see, side (AB) corresponds to side (DE), therefore, multiply the length of (AB) by () to get the side of (DE).

AB * = DE

Substitute,

Simplify,

() is another way of naming segment () this is explicitly clear from the diagram of the tirnagles.
