Answer:
C.
Step-by-step explanation:
The coefficients of the expansion of (a + b)^2 are 1 2 1, which is the third row of Pascal's triangle.
For (a + b)^3 they are 1 3 3 1 which is in the 4th row, and so on
So those for the (a + b)^n are in the (n + 1)th row.

Answer:
12.5
Step-by-step explanation:
A 10x10 grid would have 100 units. If you divide it into 8 equal units you would do:
100 / 8
Which gets you, 12.5
C. 84
12 x 8 is the area of the whole thing but you subtract 12 because of the missing 6x2 part of the square
Proportionality, assuming constant rate. 460 dives/12 hours = x dives/3 hours. Solve for x.
