The answer is letter d because the y collum is y=y•2+1
Answer:

Step-by-step explanation:
The Given question is INCOMPLETE as the statements are not provided.
Now, let us try and solve the given expression here:
The given expression is: 
Now, the BINOMIAL EXPANSION is the expansion which describes the algebraic expansion of powers of a binomial.
Here, 
or, on simplification, the terms of the expansion are:

The above statement holds for each n > 0
Hence, the complete expansion for the given expression is given as above.
Answer:
A. x^(3/5) = y.
Step-by-step explanation:
Given x^3 = y^5
y = 5th root of x^3
y = x^(3/5) answer.
The answer is C.)
S1 = 600 (divide by 2)
S2 = 300 (divide by 2)
S3 = 150 (divide by 2)
S4 = 75 (divide by 2)
S5 = 37.5
Left side I think is A is 12 sandcastles and B is 20 sandcastles.
