this means 80% of the garden is x+180 plants. x being the number of ferns.

20%/80%=1/4 so x/x+180=1/4  x=1/4 x+45  3/4 x=45  3x=180  x=60 ferns

Step-by-step explanation:

The correct answer is option a.  216

Step-by-step explanation:

It is given that,

f(x) = 6ˣ for x = 3

To find the value of f(x)

f(x) = 6ˣ

when x = 3 we can write,

f(3) = 6³ = 6 * 6 * 6 = 216

Therefore the value of f(x) when x = 3 is 216

The correct answer is option a.  216
