I believe the answer is the last one (D), because if n is 33 than 33 + (33+1[34]) = 67.
Answer:
Part a: The coefficient of
is 
Part b: The number of terms are 23751.
Step-by-step explanation:
part a
From the given equation the

So the coefficient of any term
is given as

Similarly for the generic equation of coefficient of the term
in the equation of form
is given as

So now the coefficient of
is given as

The coefficient of
is 
Part b:
The number of terms is given as 
where m is the number of variables which are 5 here
n is the power which is 25 so the number of variables is given as

So the number of terms are 23751.
I believe that the correct answer to this question is B. because matt took more than 5 minutes .
∠ ABD = 5(2X+1)
∠ DBC = 3X+6
∠ EBC = Y +135/2
∠ ABD and ∠ DBC are linear pairs
∴ ∠ ABD +∠ DBC = 180
∴ 5(2X+1) + 3X+6 =180
solve for x
∴ x = 13
∴∠ ABD = 5(2X+1) = 5(2*13+1) = 135
∠ DBC = 3x+6 = 3*13+6 = 45
∠ ABD and ∠ EBC are vertical angles
∴ ∠ ABD = ∠ EBC = 135
∴ y +135/2 = 135
∴ y = 135/2
