Answer:

A

Step-by-step explanation:

Use foil to expand it.

y = 4 (x^2 + 7x - 9x - 63)     Combine the like terms on the right.

y = 4(x^2 - 2x - 63)              Use the distributive property to remove the brackets.

y = 4x^2 - 8x - 4*63            Combine the two multiplied factors on the right.

y = 4x^2 - 8x - 252              4* 63 = 252

The answer is A

A King in ancient times agreed to reward the inventor of chess with one grain of wheat on the first of the 64 squares of a chess
statuscvo [17]
Let's start by visualising this concept.

Number of grains on square:
1   2   4   8   16 ...

We can see that it starts to form a geometric sequence, with the common ratio being 2.

For the first question, we simply want the fifteenth term, so we just use the nth term geometric form:
T_n = ar^{n - 1}
T_{15} = 2^{14} = 16384

Thus, there are 16, 384 grains on the fifteenth square.

The second question begs the same process, only this time, it's a summation. Using our sum to n terms of geometric sequence, we get:
S_n = \frac{a(r^{n} - 1)}{r - 1}
S_{15} = \frac{2^{15} - 1}{2 - 1}
S_{15} = 2^{15} - 1 = 32767

Thus, there are 32, 767 total grains on the first 15 squares, and you should be able to work the rest from here.
