Plz me with this question! i will make you brainliest!
write an equation for the description:
the length of a rectangle is twice its width. the perimeter of the rectangle is 125 feet.

w=21 ft.

l=42 ft.

Step-by-step explanation:

It says that the length is twice the Width

The perimeter is 126 ft.

w will represent width.

So, length=2w

Perimeter involves adding. So, p= 2length + 2width.

126 ft. = 2(2W) + 2W

126(represents perimeter) = 2(2w) + 2w  

126 = 4w+2w

126= 6w

divide both sides by 6.

w=21 ft.

 After finding the width, we know in order to find the length, it has to be twice the amount of the width. So, 21x2.

Resulting in:

width= 21 ft.

length= 42 ft.

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

step-by-step explanation:

i am only able to answer the first part. i am not sure about the second part. sorry

need more info

step-by-step explanation:

what do you mean by "representation"? graph? table? etc.
