Answer:
15
Step-by-step explanation:
Scale Factor = 3
Using Formula:
Scale Factor = LengthOfDilatedTraingle/LengthOfActualTriangle
Scale Factor = B'C'/B'C'
B'C' = 3 * 5
B'C' = 15
This is a combination in which you choose 4 from 10.
The formula is
combinations = 10! / 4! * (10-4)!
combinations = 10! / 4! * 6!
combinations = 10 * 9 * 8 * 7 * 6! / 4! * 6!
combinations = 10 * 9 * 8 * 7 / 4 * 3 * 2
combinations = 10 * 3 * 7
combinations = 210

---------------(1)
Here
Substituting values in equation (1)
Answer:
16x^2-24xy+9y^2.
Step-by-step explanation:
Since this is in the form of (x-y)^2, we can plug it into x^2-2xy+y^2.
So, we get 16x^2-24xy+9y^2.
