Simplify the expression below. (2n/6n+4)(3n+2/3n-2)

andrezito [222]

Answer:

$\frac{n}{3n-2}$

Step-by-step explanation:

Given the expression:

$\frac{2n}{(6n+4)} \cdot \frac{3n+2}{3n-2}$

Using the distributive property: $a \cdot (b+c) =a\cdot b+a\cdot c$

$\frac{2n}{2(3n+2)} \cdot \frac{3n+2}{3n-2}$

Simplify:

$\frac{2n}{2} \cdot \frac{1}{3n-2}$

Simplify:

$\frac{n}{3n-2}$

Therefore, the simplified given expression is, $\frac{n}{3n-2}$

What is the volume of a cone with the diameter 12 CM in height 4 cm

Romashka [77]

The formula for the volume of a cone is

$V=\pi\cdot r^2\cdot\frac{h}{3}$

to find the radius divide the diameter by 2

$\begin{gathered} r=\frac{D}{2} \\ r=\frac{12}{2} \\ r=6 \end{gathered}$

replace all data in the formula

$\begin{gathered} V=\pi\cdot(6^2)\cdot\frac{4}{3} \\ V=\pi\cdot36\cdot\frac{4}{3} \\ V=(48\pi)cm^3^{} \end{gathered}$
