Answer:

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)

L=\dfrac{2x^{2}+5x-12}{x+4}\\\\

So we can solve this through division:

         <u>  2x - 3           </u>

x + 4 | 2x² + 5x - 12

       <u> - 2x² + 8x       </u>

                  -3x - 12

                <u>- -3x - 12</u>

                       0

Given :

A boat is located a sea level. A scuba diver is 80 feet along the surface of the water from the boat and 30 feet below the water surface.

A fish is 20 feet along the horizontal plane from the scuba diver and 10 feet below the scuba diver.

To Find :

The slope between the scuba diver and fish.

Solution :

Horizontal distance between diver and fish is 20 feet.

Fish is 10 feet below the scuba diver.

Slope between scuba diver and fish is :

tan\ \theta = \dfrac{10}{20}\\\\tan\ \theta = 0.5

Therefore, the slope between the scuba diver and fish is 0.5 .
