7 0

Answer:

D

Step-by-step explanation:

f(x)=-x(x-4)

f(x)=-x²+4x

-x²+4x=0

x(-x+4)=0

x=0, x=4

(2)

4x²-x-3=0

(4x²+3x)-(4x-3)=0

x(4x+3)-1(4x+3)=0

x=1, x=-3/4

attashe74 [19]

Answer:

\frac{4}{9}\ acres

Step-by-step explanation:

To find the area of the garden, multiply the area of the backyard by 1/3

so

\frac{4}{3}(\frac{1}{3})=\frac{4}{9}\ acres
