In the diagram, GB = 2x + 3..

True [87]

Answer:

<h2>10 units</h2>

Step-by-step explanation:

It's important to know that the centroid is always two-thirds of the median. Which means

$AG=\frac{2}{3}FA\\ x+9=\frac{2}{3}(5x+x+9)\\ x+9=\frac{2}{3}(6x+9) \\x+9=4x+6\\9-6=4x-x\\3x=3\\x=1$

Which means $AG=x+9=1+9=10$ .

But, the centroid has always the same distance from each vertex, which means

$AG=BG=10$

Therefore, BG is 10 units long.

aliina [53]

Answer:

$\ln x(x^2 + 1)^\frac{1}{3} = \ln x + \dfrac{1}{3} \ln (x^2 + 1)$

Step-by-step explanation:

We are given the following expression in the question

$\ln x(x^2 + 1)^\frac{1}{3}$

Logarithmic Properties:

$\log (ab) = \log a + \log b\\\\\log \dfrac{a}{b} = \log a - \log b\\\\\log (a^b) = b\log a$

We have to simplify the given expression

$\ln x(x^2 + 1)^\frac{1}{3}\\=\ln x + \ln (x^2 + 1)^\frac{1}{3}\\\ln x + \dfrac{1}{3} \ln (x^2 + 1)$

$\ln x(x^2 + 1)^\frac{1}{3} = \ln x + \dfrac{1}{3} \ln (x^2 + 1)$
