Answer:
Letters can be chosen in 12 different ways, if order matters, or 6 different ways, if order doesn't matter.
Step-by-step explanation:
Since we want to choose 2 letters, without replacement, from the 4 letters A, B, C, and D, to determine in how many ways can this be done, if the order of the choices matters, and in how many ways can this be done, if the order of the choices does not matter, the following calculations must be performed:
If order matters =
(4 x 3 x 2 x 1) / 2 = X
24/2 = X
12 = X
If the order doesn't matter =
12/2 = X
6 = X
Therefore, letters can be chosen in 12 different ways, if order matters, or 6 different ways, if order doesn't matter.

Answer:
27.5
Step-by-step explanation:
first you find what 30x30 is as A squared plus B squared is equal to C squared. your A is 12 and your C is 30.
so!
30x30 is 900
12x12 is 144
subtract 144 from 900 and you get 756. once you find the square root you get 27.49. then round up to 27.5
Answer:A= 1,2 B=1,2 C=-9,10
Step-by-step explanation:
For A=
To find A', reflect the triangle exactly over the y-axis. That will put your A' at (1,2)
For B=
translate the triangle clockwise around the origin, (0,0), to put B' at (1,2)
For C= Translate point C to the left 4, and up 2, so the answer is (-9,10)
