Answer:

\displaystyle \frac{(a - b)^{2} - {c}^{2} }{{a}^{2} - {(b+ c)}^{2} } + \frac{(b - c)^{2} - {a}^{2} }{{b}^{2} - {(c+ a)}^{2} } + \frac{(c - a)^{2} - {b}^{2} }{{c}^{2} - {(a+ b)}^{2} }=1

Step-by-step explanation:

<u>Algebra Simplifying</u>

We are given the expression:

\displaystyle T=\frac{(a - b)^{2} - {c}^{2} }{{a}^{2} - {(b+ c)}^{2} } + \frac{(b - c)^{2} - {a}^{2} }{{b}^{2} - {(c+ a)}^{2} } + \frac{(c - a)^{2} - {b}^{2} }{{c}^{2} - {(a+ b)}^{2} }

We need to repeatedly use the following identity:

(a^2-b^2)=(a-b)(a+b)

For example, the first numerator has a difference of squares thus we factor as:

(a - b)^{2} - {c}^{2} =(a-b-c)(a-b+c)

The first denominator can be factored also:

{a}^{2} - {(b+ c)}^{2} = (a-b-c)(a+b+c)

Applying the same procedure to all the expressions:

\displaystyle T=\frac{(a - b- c)(a-b+c) }{a-b-c)(a+b+c) } + \frac{(b - c - a)(b-c+a) }{(b-c-a)(b+c+a) } + \frac{(c - a-b)(c-a+b) }{(c-a-b)(c+a+b)}

Simplifying all the fractions:

\displaystyle T=\frac{a - b- c}{a+b+c} + \frac{b-c+a}{b+c+a } + \frac{c-a+b }{c+a+b}

Since all the denominators are equal:

\displaystyle T=\frac{a - b+ c+b-c+a+c-a+b}{a+b+c}

Simplifying:

\displaystyle T=\frac{a +c+b}{a+b+c}

Simplifying again:

T = 1

Thus:

\boxed{\displaystyle \frac{(a - b)^{2} - {c}^{2} }{{a}^{2} - {(b+ c)}^{2} } + \frac{(b - c)^{2} - {a}^{2} }{{b}^{2} - {(c+ a)}^{2} } + \frac{(c - a)^{2} - {b}^{2} }{{c}^{2} - {(a+ b)}^{2} }=1}

What is the value of x?<br> 4x − 6 = 18
tensa zangetsu [6.8K]
You need to get rid of -6 by adding 6, you also need to add 6 to 18.

4x = 24

Now you need to get rid of the 4 attached to the variable, you do this by dividing 4 since it is multiplying, also dividing 4 and 24

x = 6

So the value of x is 6

Hope this helps! :)

In ABCD, the measure of ZD=90°, BD = 20, CB = 29, and DC = 21. What is the value
Nookie1986 [14]

Answer:

  0.72

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that the relation of interest is ...

  Cos = Adjacent/Hypotenuse

Then the cosine of angle C is ...

  cos(C) = CD/CB = 21/29

  cos(C) ≈ 0.72
