Using the triangle of pascal we have that the expression equivalent to (x + y) ^ 6 is given by:
x ^ 6 + 6x ^ 5y + 15x ^ 4y ^ 2 + 20x ^ 3y ^ 3 + 15x ^ 2y ^ 4 + 6xy ^ 5 + y ^ 6
Therefore, the coefficients of the expansion are given by:
1, 6, 15, 20, 15, 6, 1
Answer:
The coefficients corresponding to k = 0, 1, 2, ..., 6 in the expansion of (x + y) ^ 6 are 1, 6, 15, 20, 15, 6, 1
Well, one quarter of 20 is 5 (because 20 ÷ 4 = 5). so, to find 3 quarters, we multiply 5 times 3.
5 × 3 = 15, so 3 quarters of 20 is 15.
I think the answer is D. 170 but if I’m wrong I’m totally srry

Answer:
In a herd no. of Cattle are: x
The ratio of bulls to cows is 1:6
\frac{bulls}{cows} = \frac{1}{6}
6 bulls = 1 cows
bulls \: + cows = x
bulls + 6 \: bulls \: = x
7bulls = x
