D.

Where (h, k) is the center of the circle and the radius is squared.
Calculating for slope:
y2-y1 = m(x2-x1)
7-2 = m(2-1)
m= 5
y=mx+b
y=5x+2
Your answer would look like this

Answer:</h2>
The expression which represents the perimeter P of the rectangle as a function of L is:

<h2>
Step-by-step explanation:</h2>
The length and width of a rectangle are denoted by L and W respectively.
Also the diagonal of a rectangle is: 10 inches.
We know that the diagonal of a rectangle in terms of L and W are given by:

( Since, the diagonal of a rectangle act as a hypotenuse of the right angled triangle and we use the Pythagorean Theorem )
Hence, we have:

But we know that width can't be negative. It has to be greater than 0.
Hence, we have:

Now, we know that the Perimeter of a rectangle is given by:

Here we have:

-4.878-(-8.96) can be changed to -4.878 + 8.96 because when you subtract a negative it becomes a positive so the answer would be 4.082 or B
