Ratios
The small rectangle had length of x and width of x + 3
The large rectangle had a length of 3x and a width of x^2 + 7x + 12

Question

anonymous · Answer

I know I'd end up having:
3(x^2 + 7x + 12) = 3x(x + 3)

anonymous · Answer

which would be:
3x^2 + 21x + 24 = 3x^2 + 9x

anonymous · Answer

is x^3 + 4x^2 + 3x but what is the simplified form?

anonymous · Answer

let me know if i did anything wrong in the steps

anonymous · Answer

HOW can i put it in simplified form?

mertsj · Answer

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

mertsj · Answer

$$\frac{1}{x}=\frac{1}{x+4}$$

mertsj · Answer

$$x+4=x$$

mertsj · Answer

$$4=0$$

mertsj · Answer

No solution

anonymous · Answer

But these are my options:
3(x + 4)
x + 3 /x^2 + 7x + 12
3x /x + 4
1 /3x + 4

I don't think you posted the problem correctly because you ask what is the value of x in the proportion and then you list a bunch of answers that contain x.

mertsj · Answer

So either you have posted the wrong question or the wrong proportion.

anonymous · Answer

Oh Im so sorry!!! I posted the wrong question! Its the simplified proportion I think
