Simplifying $\frac{\frac{4x^2+2x}{x^2+x-2}}{\frac{8x^2+4x}{3x^2+10x+8}}$ we get $=\frac{3x+4}{2(x-1)}$

Option D is correct.

Step-by-step explanation:

We need to simplify:

$\frac{\frac{4x^2+2x}{x^2+x-2}}{\frac{8x^2+4x}{3x^2+10x+8}}$

It can be written as:

$\frac{4x^2+2x}{x^2+x-2}\div {\frac{8x^2+4x}{3x^2+10x+8}\\=\frac{2x(2x+1)}{x^2+2x-x-2}\div {\frac{4x(2x+1}{3x^2+6x+4x+8}\\=\frac{2x(2x+1)}{x(x+2)-1(x+2)}\div {\frac{4x(2x+1}{3x(x+2)+4(x+2)}\\$

$=\frac{2x(2x+1)}{(x-1)(x+2)}\div {\frac{4x(2x+1)}{(3x+4)(x+2)}$

Converting division sign into multiplication:

$=\frac{2x(2x+1)}{(x-1)(x+2)}\times \frac{(3x+4)(x+2)}{4x(2x+1)}\\$

Simplifying:

$=\frac{3x+4}{2(x-1)}$

So, simplifying $\frac{\frac{4x^2+2x}{x^2+x-2}}{\frac{8x^2+4x}{3x^2+10x+8}}$ we get $=\frac{3x+4}{2(x-1)}$

Option D is correct.

The length of a rectangle is twice it's width. the perimeter of the rectangle is 126 feet.

GarryVolchara [31]

Length= 47.25
Width = 15.75
47.25 x 2 = 94.5
15.75 x 2 = 31.5
31.5 + 94.5 = the total perimeter of 126.
