Answer:
c=18
Step-by-step explanation:
7/4 because you times 4 and 1.then add 3 and you get 7 so 7/4
So to rewrite it so that we can find the side, we just need to isolate the a variable.

So firstly, divide by 6 on both sides of the equation: 
Next, square root each side, and your answer should be 
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 :

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