The positive value for x is 7
Explanation:
Given that the area of a rectangle is expressed by 
The area of the rectangle is 45.
We need to determine the positive value for x.
<u>The value for x:</u>
The value of x can be determined by equating both the values of area of a rectangle.
Thus, we have,

Subtracting both sides by 45, we have;

Let us solve the equation using the quadratic formula.
Thus, we get;

Simplifying, we get;



Thus, the two values of x are given by
and 
and 
and 
Since, x cannot take negative values, then 
Thus, the value of x is 7.

4. -3.2
Step-by-step explanation:
use the quadratic formula to find x intercepts
First find the difference of the numerator. to do this multiply 1/x by 2 and 1/2 by x. you should get (2-x)/2x. now moving on to the whole fraction. then multiply the (2-x)/2x by 2x and the (x-2) by 2x. you should get (2-x)/(2x)(x-2). now factor out a negative from the (x-2) at the denominator to get -(2-x). so now you can cancel the (2-x) from the numerator and denominator! the answer will be 1/-2x! :)
