Answer:

-36

Step-by-step explanation:

since you say x=-1and y=3, you will put 1 in where x is and 3 where y is ,that is 2(3×-1]-5×3)

2(-3-15) then you subtract the bracket, that is 3-15 and it will give you -18. Then you use the 2 outside the bracket to multiply -18 ,that is 2×-18then it will give -36

A group of k elements can be chosen from a group of n elements in $\frac{n!}{k!(n-k)!}$ ways.

$(^6 _3)=\frac{6!}{3!(6-3)!}=\frac{6!}{3! \times 3!}=\frac{3! \times 4 \times 5 \times 6}{3! \times 6}=4 \times 5=20$

There are 20 different 3-member groups.
