What is the answer to x^2-11=25 please

Westkost [7]

Hey there!

$\mathsf{x^2 - 11 = 25}$

$\large\textsf{ADD 11 to BOTH SIDES}$

$\mathsf{x^2 - 11 + 11 = 25 + 11}$

$\large\textsf{CANCEL out: -11 + 11 because that gives you 0}$

$\large\textsf{KEEP: 25 + 11 because that helps solve for the x-value}$

$\mathsf{25 + 11 = \bf 36}$

$\large\textsf{NEW EQUATION: }\mathsf{x^2=36}$

$\large\textsf{Take the square root of the number (36)}$

$\mathsf{x = \pm \sqrt{36}}$

$\mathsf{\pm = \boxed{\bf plus-or-minus}}$

$\mathsf{x = \sqrt{-36}\rightarrow \bf -6}$

$\large\textsf{or}$

$\mathsf{x = \sqrt{36} = \bf 6}$

$\boxed{\boxed{\huge\textsf{Answer: \bf x = 6 or x = -6}}}\huge\checkmark$

$\large\text{Good luck on your assignment and enjoy your day!}$

Please find the derivative of <img src="https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7Be%5E%7B%5Cfrac%7B3%7D%7Bx%7D%7D%7D%7

Hello! :)

$\large\boxed{\frac{-e^{\frac{3}{x}} (3 + 2x )}{x^{4}}}$

Find the derivative using the quotient rule:

$\frac{f(x)}{g(x)} = \frac{g(x) * f'(x) - f(x) * g'(x)}{(g(x))^{2}}$

In this instance:

$f(x) = e^{\frac{3}{x} }\\\\g(x) = x^{2}$

Use the following properties to find the derivative of f(x) and g(x):

$e^{u} = u' * e^{u}\\\\x^{n} = nx^{n-1}$

Use the quotient rule:

$\frac{x^{2} * (e^{\frac{3}{x}} * (-3x^{-2})) - e^{\frac{3}{x}} * 2x }{(x^{2} )^{2}}$

Simplify the numerator:

$\frac{(e^{\frac{3}{x}} * (-3)) - e^{\frac{3}{x}} * 2x }{(x^{2} )^{2}}$

Factor out $e^{\frac{3}{x}}$

$\frac{e^{\frac{3}{x}} (-3 - 2x )}{x^{4}}$

Factor out -1 from the numerator:

$\frac{-e^{\frac{3}{x}} (3 + 2x )}{x^{4}}$

And we're done! Thanks for posting the question to my 1000th answer!

What is the length of BC in the right triangle below?

m_a_m_a [10]

Answer:

20

Step-by-step explanation:

a^2 + b^2 = c^2

12^2 + 16^2 = c^2

144 + 256 = c^2

400 = c^2

20 = c

The length of BC = 20
