A function k whose domain is the set of positive integers is defined as k(1)=4 and k(n)=k(n−1)−2. Function k was evaluated for several numbers. Which of the following are true? k(-1)- -4
k(0)= -2
k(2)= 2
k(3)=0
k(6)=3
HELL PLEASE

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

6mm^3 or .6cm^3

factor trees are nice.
