The length of a rectangular field is 20 less than its width. the area of the field is 12,000 ft2. what is the width of the field? 80 ft 100 ft 120 ft 140 ft

120 ft.

Step-by-step explanation:

Given: The length of a rectangular field is 20 less than its width.

Let w be the width of the rectangle, then the length of the rectangle will be w-20

We know that the area of rectangular field is given by :-

If w =120, then l= 120-20=100ft

and

But, it w=100, then l= 100-20=80 ft.

and , which is not the area of the field.

hence, the width of the rectangular field = 120 ft.

all but the second one

step-by-step explanation:

cuz that one goes over 180

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
