Question

It would be nice if someone can help me

Answer 1

Solution is 16r-14s

Explanation:

2(7r-2s)+2(r-5s)

14r-4s+2r-10s

16r-14s

Answer 2

16r - 14s

Explanation:

The perimeter is a measure of a polygon that describes the distance around the boundaries of a shape.

Perimeter Formula

The perimeter of a rectangle is equal to
`l + l + w + w`, where
`l` is the length and
`w` is the width. This can be simplified to
`2l+2w`. Now, we can plug in the expression we are given for width and length.

• 
  `2(r-5s)+2(7r-2s)`

Simplifying the Expression

The expression above does accurately depict the perimeter, but it should be simplified to make the expression easier to understand and use.

First, distribute the 2 inside the parentheses.

• 
  `2r-10s+14r-4s`

The next step is to combine like terms. Like terms are terms that have the same power and variable. For example, 2r and 14r are like terms.

• 16r - 14s

This is the simplified expression and the final answer.
