vovangra [49]
Six (6) less than (subtraction) six (6) times (multiplication) a number (n) is (=) 12.

6n - 6 = 12  

To solve, add 6 to both sides

6n = 18   Dviide both sides by 6
  n = 3

Tyler has 120 linear feet of fencing to put around his garden. If he uses the fence to border a rectangular garden, what is the
Travka [436]

Answer:

The maximum area is 900\ ft^{2}

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

P=2(x+y)

we have

P=120\ ft

so

120=2(x+y)

60=(x+y)

y=60-x------> equation A

Remember that

The area of rectangle is equal to

A=xy -----> equation B

substitute equation A in equation B

A=x(60-x)

A=-x^{2} +60x

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 (30,900)

see the attached figure

Find the value of y

y=60-x ----->  y=60-30=30\ ft

The dimensions of the rectangular garden is 30\ ft by 30\ ft

For a maximum area the garden is a square

The maximum area is 900\ ft^{2}
