Simplify the equation

Arturiano [62]

Answer:

$\dfrac{16x^3-37x^2-16x+37}{x^2+2}$

Step-by-step explanation:

There aren't any factors that cancel (except 3x). The best you can do is multiply it out.

$\displaystyle\frac{\frac{3x^2-3}{x}}{\frac{3(x^2+2)}{16x^2-37x}}=\frac{3(x^2-1)}{x}\cdot\frac{16x^2-37x}{3(x^2+2)}\\\\=\frac{x(x^2-1)(16x-37)}{x(x^2+2)}=\frac{16x^3-37x^2-16x+37}{x^2+2}$

Solve for the variable in 6⁄18 = x⁄36 A. 12 B. 6 C. 3 D. 9

RoseWind [281]

$\dfrac{6}{18} = \dfrac{x}{36}$

$\dfrac{1}{3} = \dfrac{x}{36}$

$\dfrac{1}{3} * 36 = x$ $|Multiply \ by \ 36|$

$x= \dfrac{36}{3}$ $|Divide \ both \ sides \ by \ 3|$

$x=12$
