Patricia wishes to have a rectangular-shaped garden in her backyard. she has 82 ft of fencing material with which to enclose her garden. letting x denote the width of the garden, find a function f in the variable x giving the area of the garden. what is its domain?

width=x

perimeter=80

or 2(x+l)=80

so l=length=40-x

so the area=x(40-x)

the area can never be 0

x(40-x)>0

this gives the domain as 0

Step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
