The area of a rectangle is 64 square inches. express the perimeter p as a function of the w
and state the domain.

Step-by-step explanation:

The area of a rectangle is A = lw.  If the area is 64, we sub it in to get 64 = lw.

If we want to express the perimeter in terms of w using that area expression, we solve the area for l:

The formula for the perimeter of a rectangle is

P = 2l + 2w

If we are to express it in terms of w, sub in the l value from the area:

which simplifies to

Because this is width and width is a distance measure, it can't ever be negative or 0, so the domain for w is w > 0.

Perimeter   P=2x+ (128/x)

Step-by-step explanation

Area = L*W

Perimeter = 2L + 2W

one side is x meters

area = 64 sq.inches

 the other side will be 64/x.  

the perimeter P = 2L+2W

P= 2x+ (2*64/x)

P=2x+ (128/x)

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

i believe the answer is d.

hope it you! : d
