Question

could someone please help me and explain how to do this!!!!

I have to find its width

Answer 1

Hi there, 

the area is (4$x^{4}$ +8$x^{2}$ + 14)

so,

the area divided by the length ( find width ), which is:

(4$x^{4}$ +8$x^{2}$ + 14) ÷ 2$x^{2}$

So,

The answer is $\frac{2 x^{4}+4 x^{2}+7}{ x^{2} }$

Hope this helped :p
