Aswimming pool has an area of 2x² + 5x - 12. if the width of the swimming
pool is (x + 4), what is the length of the swimming pool?

2x - 3

Step-by-step explanation:

The are of a rectangle is computed using the formula:

A = L x W

The area given is:

2x² + 5x -12

So:

2x² + 5x -12 = L x (x + 4)

So we can solve this through division:

           2x - 3          

x + 4 | 2x² + 5x - 12

        - 2x² + 8x      

                  -3x - 12

                - -3x - 12

                       0

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
