Please show your work and explain it.

Answer:

f(x)=\dfrac{x+2}{2(x-2)}

Step-by-step explanation:

Remember when you divide fractions, you need to get the reciprocal of the divisor and multiply. So your first simplification would be:

\dfrac{x^2+4x+4}{x^2-6x+8}\div\dfrac{6x+12}{3x-12}\\\\=\dfrac{x^2+4x+4}{x^2-6x+8}\times\dfrac{3x-12}{6x+12}\\\\=\dfrac{(x^2+4x+4)(3x-12)}{(x^2-6x+8)(6x+12)}

Next we factor what we can so we can further simplify the rest of the equation:

=\dfrac{(x^2+4x+4)(3x-12)}{(x^2-6x+8)(6x+12)}\\\\=\dfrac{(x+2)(x+2)(3x-12)}{(x^2-6x+8)(6(x+2))}\\\\

We can now cancel out (x+2)

=\dfrac{(x+2)(3x-12)}{(x^2-6x+8)(6)}

Next we factor out even more:

=\dfrac{(x+2)(3)(x-4)}{(x-2)(x-4)(6)}

We cancel out x-4 and reduce the 3 and 6 into simpler terms:

=\dfrac{(x+2)(1)}{(x-2)(2)}

And we can now simplify it to:

=\dfrac{x+2}{2(x-2)}

Answer:

  (b)  36.56 ft

Step-by-step explanation:

The perimeter is the total of the circumference of a 4 ft circle and two lengths that are 12 ft.

The circumference is given by ...

  C = πd

  C = (3.14)(4 ft) = 12.56 ft

Adding the 24 ft of straight sections, we find the total perimeter to be ...

  P = 12 + 12 + 12.56 = 36.56 . . . feet

Lynn asked six friends how many cars their parents own. She recorded 1, 1, 2, 2, 2, and 4 cars. What is the mean absolute deviat
galben [10]
To find the mean absolute deviation, you have to find the mean first.
1+1+2+2+2+4=12
12 divided by 6 numbers=2         The mean of that is two
Next, you have to find the amount the original numbers are away from the mean.
1= 1 away from 2               2=0 away from 2               4=2 away from 2
You should get: 1,1,0,0,0,2              Next, you have to find the mean of the new set of numbers.    1+1+0+0+0+2=4
4 divided by 6= 2/3
The mean absolute deviation is 2/3
