Answer:

x = 10

Step-by-step explanation:

The marked sides are proportional, so we have ...

x/8 = (x +5)/12

3x = 2(x +5) . . . . . multiply by 24 to clear fractions

3x = 2x + 10 . . . . . eliminate parentheses

x = 10 . . . . . . . . . . subtract 2x

_____

<em>Alternate solution</em>

We observe that the difference between the upper segment lengths is ...

(x +5) -(x) = 5

and the difference between the lower segment lengths is ...

12 -8 = 4

This means the upper segment lengths are 5/4 times as long as the lower segments. Then ...

x = (5/4)(8) = 10

Rewrite in logarithmic form 19^2 = 361

Aneli [31]

Answer:

$\log_{19}{361}=2$

Step-by-step explanation:

We know that taking logarithms performs the transformation ...

$b^e=x\\\\e\cdot\log{b}=\log{x}\quad\text{take logs}\\\\e=\dfrac{\log{x}}{\log{b}}\quad\text{divide by $\log{b}$}\\\\\log_b{x}=e\quad\text{use the change of base formula}$

Then for b=19, e=2, x=361, we have

$\boxed{\log_{19}{361}=2}$
