Answer:

z = 1/9   and    z = 1

Step-by-step explanation:

-9 z^{2} + 10z - 1 = 0

(-9z+1)(z-1) = 0

You can check the answer using foil method

Then,

(-9z+1) = 0

-9z = -1

z = 1/9

(z-1) = 0

z = 1

Answers:

z = 1/9

z = 1

Pilaf has a circular garden plot with an area of 125 square feet. To fence the area, how many feet of fencing does she need?
Jet001 [13]
So, to find the find the amount of fencing required, or the circumference of the gardening, pot...

Area = pi * r^2
125 square feet = pi *r^2
125/ pi = r^2
39.79 = r^2
root square of 39.79 = r
6.31 = r

To find the circumference, the formula is: pi * D (or Pi * r * 2)

therefore, 

C = pi * 6.31 *2
C = 39.65 feet

therefore, 39.65 feet of fencing is needed.
