Answer:

Step-by-step explanation:
We are to determine which of these expressions are equivalent to: 




Therefore, the two equivalent expressions are:

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.
3.1
the number of trucks reading horizontally from the vertical scale is
2 + 2 + 3 + 3 + 3 + 4 + 5 = 22
average number of trucks =
= 3.1 ( to 1 dec. place)
It will take about 22 minutes because 20 hours divided by 15 rooms equals 1 hour and 33 minutes for one room divided by the six painters equals 22 minutes
