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

30+6p=7p+42-5

30+6p=7p+37

-7=p

p=-7
