I am repeating again the solution, although I don't think there was a mistake:
0.36 (with the bar over 36) means the number under the is repeating itself, we call it a recurring decimal.
So 36 ,with a bar over 36 means: 0.3636363636....
To write any recurring decimal in a fraction, you have to multiply & divide at the same, the number with 100 , if you choose 0.36 or with 10,000 if you choose 0.3636 or with 1,000,000 if you choose 0.363636 (note that the number of Zeros equal the number of chosen decimals.
In our example let's take 0.3636 , then we multiply it by 10,000 & divide it by same: (0.3636 x 10,000) = 3636/10,000 =1,818/5,000 = 909/2500 =0.3636
If you opt to render 0.363636 into a fraction, then you have to multiple the latter number & divide it by 1,000,000
Answer: 
Step-by-step explanation:
Answer:
-1.5 or -6/4
Step-by-step explanation:
Im assuming the equation is 4x+6=0
1.) subtract the 6 from each side.
4x= -6
2.) you need to isolate the X, so divide the 4 from each side.
X= -6/4 or -1.5
Answer:
C
Step-by-step explanation:
9x^2-49y^2
Answer:
The maximum area is 
Step-by-step explanation:
Let
x----> the length of rectangle
y---> the width of rectangle
we know that
The perimeter of rectangle is equal to
we have
so
------> equation A
Remember that
The area of rectangle is equal to
-----> equation B
substitute equation A in equation B
This is a vertical parabola open downward
The vertex is a maximum
The y-coordinate of the vertex of the graph is the maximum area of the garden and the x-coordinate is the length for the maximum area
using a graphing tool
The vertex is the point 
see the attached figure
Find the value of y
-----> 
The dimensions of the rectangular garden is 
by
For a maximum area the garden is a square
The maximum area is
