Step-by-step explanation:

1/3(9k+12)=15

We move all terms to the left:

1/3(9k+12)-(15)=0

Domain of the equation: 3(9k+12)!=0

k∈R

We multiply all the terms by the denominator

-15*3(9k+12)+1=0

Wy multiply elements

-45k(9+1= 10

Mandy is building a rectangular garden pond with the area of 12ft^2. The length of pool needs to be 2 ft more than twice the wid
Genrish500 [490]

The length of rectangular pool is 6 ft and width of rectangular pool is 2 ft.

Step-by-step explanation:

Given,

Area of rectangular pool = 12 square feet

Let,

Width of pool = w

Length of pool = l = 2w+2

Area = Length * Width

12=(2w+2)*w\\12=2w^2+2w\\2w^2+2w-12=0

Dividing each term by 2;

\frac{2w^2}{2}+\frac{2w}{2}-\frac{12}{2}=0\\w^2+w-6=0\\w^2+3w-2w-6=0\\w(w+3)-2(w+3)=0\\(w+3)(w-2)=0\\

Either,

w+3 = 0       => w=-3

Or,

w-2=0          =>w=2

As width cannot be negative, therefore,

Width of rectangular pool = 2 ft

Length of rectangular pool = 2w+2 = 2(2)+2 = 4+2 = 6 ft

The length of rectangular pool is 6 ft and width of rectangular pool is 2 ft.
