Lesechka [4]

<u>Answer:</u>

a = 7.4

<u>Step-by-step explanation:</u>

<u>We can find 'a' through Pythagoras theorem.</u>

=> 8² = 3² + a²
=> 64 = 9 + a²
=> a² = 55
=> a = √55
=> a = 7.416 = 7.4

Step-by-step explanation:

Just solve the equation 5-√x = 3

So, let’s solve it:

5-√x = 3 ⇔ 5-3=√x ⇔ √x = 2 ⇔ x=4

Then ?=4

(11/x^2-25)+(4/x+5)= 3/x-5

Ierofanga [76]

$\bf \textit{difference of squares}
\\ \quad \\
(a-b)(a+b) = a^2-b^2\qquad \qquad 
a^2-b^2 = (a-b)(a+b)\\\\
-------------------------------\\\\
\cfrac{11}{x^2-25}+\cfrac{4}{x+5}=\cfrac{3}{x-5}\implies \cfrac{11}{x^2-5^2}+\cfrac{4}{x+5}=\cfrac{3}{x-5}$

$\bf \cfrac{11}{(x-5)(x+5)}+\cfrac{4}{x+5}=\cfrac{3}{x-5}\impliedby 
\begin{array}{llll}
\textit{notice, LCD is }(x-5)(x+5)\\
\textit{so let's multiply all by it}\\
\textit{to toss the denominators}
\end{array}$

$\bf (x-5)(x+5)\left( \cfrac{11}{(x-5)(x+5)}+\cfrac{4}{x+5} \right)=(x-5)(x+5)\left( \cfrac{3}{x-5} \right)
\\\\\\
11+4(x-5)=3(x+5)\implies 11+4x-20=3x+15
\\\\\\
4x-9=3x+15\implies x=24$
