Acarpet has a rectangular measure of 10 feet for the length and w feet for the width. if the perimeter is the sum of all four sides, then write an expression that represents the perimeter. simplify. 2w – 20 2w – 10 2w +10 2w + 20

2w + 20

Step-by-step explanation:

See, the carpet has a rectangular measure of 10 feet.

It's width is 'w'

We, know that perimeter is the sum of all sides.

Now there are two equal sides which we consider length and two other equal sides for width.

So, we have to add all sides which gives 20 +2w

Also general formula for perimeter is 2(length + breadth)

So, our ans. is 2w + 20

Hope it helps!!!

Always the same variable.

Step-by-step explanation:

When the question says "x is always constant", it means that the x variable does not change, and it is always the same number.
