Y=14
If they are congruent then t=d so write the equation and solve from there, welcome im Procrastinating.
Rotation about a point does not change any dimensions. C'D' = CD = 2.8 units.
What can a denominator never be?
0
so, we need to figure what x can't be... the only way to multiply 2 things together to get 0 is if one or both are zero.
so, what x values make our denominator 0?
to figure this out, we need to set (x-1)(x-2)=0
now we split and solve.

so when x is 1 or 2 the function doesnt make sense.
but, x can be every other number and it does, so the answer is
ALL REAL NUMBERS not equal to 1 or 2
4 outcomes,
Heads - Heads
Heads - Tails
Tails - Tails
Tails - Heads
With every coin added the amount of outcomes is multiplied by two
