First you graph "y = 2x +2." You shade in the region below it, because it's y "LESS THAN" and you keep the line solid (not dotted) because it's "equal to" 2x+2 too.

A rectangular garden is fenced on three sides with a wall forming on the fourth side. The total length of the fence is 120m. The

creativ13 [48]

Answer:

20m by 80m

Step-by-step explanation:

Let the dimension of the garden be x by y

The garden is fenced on three sides with a perimeter of 120m

Perimeter of the three sides = 2x+y

Therefore:

2x+y=120

The Area of the garden = $1600m^2$

xy=1600

From the first equation, y=120-2x

Substitute y=120-2x into xy=1600

xy=1600

x(120-2x)=1600

$120x-2x^2=1600\\2x^2-120x+1600=0\\2x^2-80x-40x+1600=0\\2x(x-40)-40(x-40)=0\\(2x-40)(x-40)=0\\2x-40=0\: x-40=0\\x=20 \: or \: x=40$

Recall,

xy=1600

When x=20, 20y=1600===>y=80

When x=40, 40y=1600===>y=40

So we have the pair (20,80) and (40,40).

However since we are told that the garden is rectangular, we pick the dimension with unequal sides.

The dimension of the garden is 20m by 80m.
