Answer:
A & C
Step-by-step explanation:
Factor 196k
196k=2*2*7*7*k
we need to get something like x^3
hmm
we right now have
(2*7)^2
if we multiply that by (2*7)^1, we can beg (2*7)^3,
therefor k=2*7=14
tha tnumber is 14
or
if k can be any number
k can be 1/196, to make it 1, and 1 is a perfect cube
or
my bro had an epic idea: what if k is negative
the cube root of a negative number is negative
so the smallest one would be negative infinity or something
I think the answer you're looking for is k=14
Its 72, which is answer A
No because a pentagon has more sides than a square does.
to find perimeter you have to add up all the sides.
for the square it would be 9+9+9+9 which is 36
for the pentagon it would be 9+9+9+9+9 which is 42.
37.5% of 20 is 7.5 so the answer is 37.5%
