I NEED HELP FAST PLEASE!!!!!

Answer:

Excluded values -2,0,2 These are non removable since we cannot cancel them in the numerator

(x+1)

---------

x(x+2)

Step-by-step explanation:

-2 x-1

----------- + ---------

x^2 -4 x^2 -2x

First factor the denominators

-2 x-1

----------- + ---------

x^2 -4 x^2 -2x

x^2 -4 is the difference of squares

x^2 -4 = (x-2) (x+2)

x^2 -2x has an x in common

x(x-2)

-2 x-1

----------- + ---------

(x-2)(x+2) x(x -2)

The values that are excluded are the values that make the denominators zero

(x-2) (x+2) = 0 x=2 x=-2

x(x-2) =0 x=0 x=2

Excluded values -2,0,2 These are non removable since we cannot cancel them in the numerator

We need to get a common denominator of (x-2)(x+2)x

Multiply the first term by x/x and the second term by (x+2)/(x+2)

-2 x (x-1) (x+2)

----------- + ----------------

x(x-2)(x+2) x(x -2)(x+2)

Distribute

(x+2)(x-1) = x^2 -x+2x-2 = x^2+x-2

-2 x x^2+x-2

----------- + ----------------

x(x-2)(x+2) x(x -2)(x+2)

Combine like terms, since the denominators are the same

-2 x + x^2+x-2

---------------------------

x(x-2)(x+2)

x^2-x-2

---------------------------

x(x-2)(x+2)

Factor the numerator

x^2-x-2 = (x-2) (x+1)

(x-2) (x+1)

---------------------------

x(x-2)(x+2)

Cancel like terms

(x+1)

---------------------------

x(x+2)

The excluded values are found at the beginning, not now. We canceled some of them in our simplified expression. They are still excluded values

Josh is inviting his friends to a party. He has 42 granola bars and 56 fruit drinks, and he wants to give the same number of eac

Elza [17]

Answer:

<h3>The number of granola bars that Josh gave to each of his friend is 3</h3><h3>The number of fruit drinks that Josh gave to each of his friend is 4</h3>

Step-by-step explanation:

Given Number of granola bars with Josh is 42

Number of fruit drinks with Josh is 56

He wants to give the same number of each granola bars and fruit drinks to each friend.

<h3>To find the number of granola bars and fruit drinks Josh give to each friend:</h3>

First we have to find HCF of 42 and 56 .

$42=2\times 3\times 7$

and $56=2\times 2\times 2\times 7$

$Number of granola bars that Josh gave to each of his friend =\frac{Number of granola bars with Josh}{HCF ( 42, 56 )}$

$=\frac{42}{14}$

= 3

<h3>∴ Number of granola bars that Josh gave to each of his friend is 3</h3>

$Number of fruit drinks that Josh gave to each of his friend =\frac{Number of fruit drinks with Josh}{HCF ( 42, 56 )}$

$=\frac{56}{14}$

= 4

<h3>∴ Number of fruit drinks that Josh gave to each of his friend is 4</h3>

If the exchange rate when converting US dollars to Za rands is $1=R17

den301095 [7]

<h3>Given:</h3>

1 US Dollar= R17

How much is $100 in ZA rands.

<h3>Solution:</h3>

Let the unknown be "x"

$\frac{1}{17}×\frac{100}{x}$

We'll have to do cross multiplication.

So we'll have to multiply 100 and 17.

$100×17$

$\huge\boxed{= 1700 \: ZA \: rands}$

<u>T</u><u>herefore</u><u>,</u><u> </u><u>$</u><u>1</u><u>0</u><u>0</u><u> </u><u>is</u><u> </u><u>1</u><u>7</u><u>0</u><u>0</u><u> </u><u>ZA</u><u> </u><u>rands</u><u>.</u>
