Answer:

1) \frac{1}{(x - 3)(x + 2)}  +  \frac{3}{(x + 2)(4 - x)}  +  \frac{2}{(x - 3)(x - 4)}  \\  \\  =  \frac{x - 4}{(x - 3)(x + 2)(x - 4)}  -  \frac{3(x -  3)}{(x - 4)(x + 2)(x - 3)} +  \frac{2(x + 2)}{(x + 2)(x - 3)(x - 4)} \\  \\  =  \frac{x - 4  - 3x + 9 + 2x + 4}{(x - 3)(x - 4)(x + 2)}  \\  \\  =  \frac{9}{(x  +  2)(x - 3)(x - 4)}

2) \frac{2}{(x - 2)(x - 3)}  +  \frac{2}{(x - 1)(3 - x)}  +  \frac{1}{(1 - x)(2 - x)}  \\  \\  =  \frac{2(x - 1)}{(x - 1)(x - 2)(x - 3)}  -  \frac{2(x - 2)}{(x - 1)(x - 2)(x - 3)} +  \frac{x - 3}{(x - 1)(x - 2)(x - 3)}  \\  \\  =  \frac{2x - 2 - 2x + 4 + x - 3}{(x - 1)(x  -2)(x - 3)}  \\  \\  =  \frac{x - 1}{(x - 1)(x - 2)(x - 3)}  \\  \\  =  \frac{1}{(x - 2)(x - 3)}

Answer:

f(-x)= -f(x) so, the given function f(x)= x^3-2x is Odd

Step-by-step explanation:

We need to determine if the function f(x)= x^3-2x is Even, Odd, or Neither.

Determining if a function f(x) is even or not we put x=-x and check

If f(-x)=f(x) the function is even

if f(-x)= -f(x) the function is odd

So, Putting x =-x and determining if the given function f(x)= x^3-2x is Even, Odd, or Neither.

f(x)= x^3-2x\\Put \ x=-x\\f(-x)=(-x)^3-2(-x)\\f(-x)=-x^3+2x\\f(-x)=-(x^3-2x)\\f(-x)=-f(x)

As f(-x)= -f(x) so, the given function f(x)= x^3-2x is Odd

Sharon uses 6.3 pints of blue paint and white paint to paint her bedroom walls. 4 5 of this amount is blue paint, and the rest i
Y_Kistochka [10]

Given:

Sharon uses 6.3 pints of blue paint and white paint to paint her bedroom walls.

\dfrac{4}{5}th of this amount is blue paint and the rest is white paint.

To find:

The pints of white paint did she use to paint her bedroom walls.

Solution:

We have,

Total paint used = 6.3 pints

Blue paint = \dfrac{4}{5}th of total paint used

                 = \dfrac{4}{5}\times 6.3

                 = 5.04

White paint = Total paint used - Blue paint

                   = 6.3-5.04

                   = 1.26

Therefore, Sharon uses 1.26 pints of white paint to paint her bedroom walls.
