Answer:
The length of the rectangle is 25 km
Step-by-step explanation:
Let
x ----> the length of rectangle
y ----> the width of rectangle
we know that
The perimeter of rectangle is

we have

so

simplify
---- > equation A
---> equation B
substitute equation B in equation A and solve for y





Find the value of x
therefore
The length of the rectangle is 25 km
<h2>
Hello!</h2>
The answer is: D. is the fourth picture.
<h2>Why?</h2>
First, we need to make these numbers entire or decimal numbers, in order to see where are they located:

So, we should look for the image that shows the following order it: 2.69, 4 and 4.47
or


Then, we just need to find the image where they are properly located/ordered:
So, the correct image is D. is the fourth picture.
Have a nice day!
The simplified expression of (x + y)(x - y) is x^2 - y^2
<h3>How to solve the expression?</h3>
The expression is given as:
(x + y)(x - y)
Expand the bracket
x(x - y) + y(x -y)
Further, expand
x^2 - xy + xy - y^2
Evaluate the like terms
x^2 - y^2
Hence, the simplified expression of (x + y)(x - y) is x^2 - y^2
