Answer:

BC = 50

Step-by-step explanation:

I believe what I'm doing is correct but to be completely honest with you, I haven't done this in a while lol

Okay so...

You would do

1. 6y-16 = 4y+6

You would subtract 4 from 6...

2. 2y-16 = 6

You would then add 16 to 6...

3. 2y = 22

Then, divide 2 from 22...

4. y = 11

Substitute into BC...

5. 6 (11) - 16 = 66 - 16 = 50

Then, you get your final answer...

6. BC = 50

I hope it's right. Good luck ^^

Answer:

b. $\frac{1}{3}$

Step-by-step explanation:

The scale factor is the number by which one must multiply all sides in a triangle such that its sides are the same as another triangle. This only works in similar triangles (triangles where all of the angles between them are congruent or have the same measures).

Step-by-step explanation:

5(5)^(n-1) = 78,125

= 5/4 (78, 125 -1)
