Answer:

8x-2

Step-by-step explanation:

l = x+4

w = 3x-5

The perimeter is

P =2(l+w)

= 2(x+4+3x-5)

Combine like terms

= 2(4x-1)

Distribute

= 8x-2

Answer:

$8x-2$

Step-by-step explanation:

The perimeter of a rectangle is 2L + 2W, where L represents the length and W represents the width. In this scenario, L is equal to x + 4 and W is equal to 3x - 5. We can setup an equation:

$2(x+4)+2(3x-5)$

We can then multiply x - 4 by 2 to get $2x+8$

We can then multiply 3x - 5 by 2 to get $6x-10$

Adding them together, we get the answer as $8x-2$

If x represents an integer how would you express its negative

Oxana [17]

Answer: $-x$

Step-by-step explanation:

It is important to remember that:

- Integers contains the positive numbers (+), negative numbers (-) and zero.

- The numbers greater than zero are Positive Integers.

- The numbers less than zero are Negative integers.

- An integer and its opposite have the same distance from zero, but they are located on opposite sides of the number line.

In this case we know that $x$ is a Positive Integer, therefore, based on the information mentioned before, we can say that its negative (or its opposite) is:
