Rectangle has an
The area of a rectangle can be expressed by 2^2- 7x - 4.
area of 45, find the positive value for x.

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.

The value for x:

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.

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this
