= A/x +B/(x -2) +C/(x -4)
To find A, multiply the expression by x and evaluate at x=0.
.. A = 24/((-2)*(-4)) = 3
To find B, multiply the expression by x-2 and evaluate at x=2.
.. B = (18*2^2 -68*2 +24)/(2*(2-4)) = -40/-4 = 10
To find C, multiply the expression by x-4 and evaluate at x=4.
.. C = (18*4^2 -68*4 +24)/(4(4 -2)) = 40/8 = 5
The partial fraction decomposition is
.. = 3/x +10/(x -2) +5/(x -4)
<em>Greetings from Brasil...</em>
According to the statement of the question, we conclude that the area of a square is requested, whose value is 171 in²
The area of a square is given by the expression:
A = S²
<em>where S is the side of the square - just what we want to know</em>
So:
A = S²
171 = S²
√171 = S
<h3>S ≈ 13.08in</h3>

Answer: Choice B) 15.7</h3>
======================================================
Explanation:
Use the distance formula to find the distance from point A to point B
This means segment AB is approximately 2.8284 units long.
Repeat those similar steps to find the following other side lengths:
Side note: this figure is a parallelogram with congruent pairs of opposite sides
Now add up the four exterior sides to get the perimeter
perimeter = AB+BC+CD+AD
perimeter = 2.8284+5+2.8284+5
perimeter = 15.6568
perimeter = 15.7 units
