Step-by-step explanation:
Given in the question,
C(8,2)
Formula to use:
nCr = n! / r! * (n - r)!
here n = 8
r = 2
We have to calculate combinations of 8 object taken 2 at a time, then
C(8,2)
8C2
8! / 2! * (8 - 2)!
56/2
28
So, 8C2 = 28
The rule to rotate the figure is (-y,x) making point A (4,0).

Karenanya,
Pembelian pertama + pembelian tambahan
2k + 5
Oleh karena itu, ungkapan aljabar untuk Beras yang dibeli oleh Pak Veri dalam kg:
2k + 5
k diberikan dalam kg
