Six less than six timesa number is 12

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

$P=120\ ft$

$120=2(x+y)$

$60=(x+y)$

$y=60-x$ ------> 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 $900\ ft^{2}$
