Please help me and please show all your work because I am looking for how can I do it

P = 48 is the perimeter

W = width

L = length = 2*W

perimeter of rectangle = 2*(L+W)

P = 2*(L+W)

48 = 2*(2W+W) replace L with 2W

48 = 2*(3W)

48 = 6W

6W = 48

W = 48/6 divide both sides by 6

W = 8

L = 2*W

L = 2*8 plug in W = 8

L = 16

The rectangle has a length and width of 16 feet and 8 feet.

Check:

P = 2*(L+W)

P = 2*(16+8)

P = 2*24

P = 48

Or you could think of it as

P = length+width+length+width

P = 16+8+16+8

P = 24+24

P = 48

The answer has been confirmed.

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
