Answer:
f=4
Step-by-step explanation:
Priya Tried to solve the equation below step-by-step:

The steps are correct and indeed f=4.
X/(x^2+3x+2) - 1/((x+2)(x+1))
x/(x^2+3x+2) - 1/(x^2+3x+2)
(x - 1)/(x^2+3x+2)
Answer: Choice D
ANSWER

EXPLANATION
The equation of the circle with radius r and centre (a,b) is given by

The radius is

We need to determine the center of the circle from the given equation of another circle, which is,

We complete the square to obtain,





The centre of this circle is (4,3)
Hence the center of the circle whose equation we want to find is also (4,3).
With this center and radius 2, the required equation is,

Therefore the correct answer is C.
Answer:
243.84
Step-by-step explanation:
We change feet to inches, and inches to cm.
1 ft = 12 in.
1 in. = 2.54 cm
8 ft * (12 in.)/(1 ft) * (2.54 cm)/(1 in.) = 243.84 cm
8 ft = 243.84 cm
Answer:
Option D, 1
Step-by-step explanation:
<u>Step 1: Determine what x1, x2, y1, y2 are</u>
Slope = 
(x1, y1) is (2, 8)
(x2, y2) is (6, 12)
<u>Step 2: Plug into the formula to get the slope</u>
Slope = 
Slope = 
Slope = 
<em>Slope = 1</em>
