Two sides of a right triangle measure 2 units and 4

fredd [130]

Hey there!

The answer is √20 or approximately 4.47

We can use the Pythagoreon Theorem, which is $a^2 +b^2=c^2$ . $a$ and $b$ are the names of the two sides, and $c$ is the name of the hypotenuse leg, or the longest side. We will plug the numbers into the formula, and solve:

$2^2+4^2=c^2\\4+16=c^2\\20=c^2\\4.47...=c$

Have a terrifcly amazing day!

Log_6⁡(x+1)+log_6⁡x=1

Fiesta28 [93]

This is pretty simple once you figure out the trick.

All you have to do is make the args common.

Meaning $log_{6}(x + 1) + log_{6}(x) = 1$ is nothing but $log_{6}(x(x + 1)) = 1$

Which is nothing but: $log_{6}(x^2 + x) = 1$ .

Now using the scorpion tail method, this equation can be reframed to being: $6 = x^2 + x$ . You bring 6 to the other side and it'll become: $x^2 + x - 6 = 0$

Factorise it and you get: $(x - 2) * (x + 3)$

Henceforth, the solution would be $2$ and $-3$ . :D
