Do Pythagorean theorem. If you don't know what that is...
Do A squared plus B squared Equals C squared and you will get your answer for the shape. Then calculate the area
The answer is A. U basically divide the price with the amount of item and pick the cheapest one :)
The equation representing this situation would be 3 + 2x = c, where c is the total cost.
To find the cost to bring 12 dogs, you will replace the x with the number 12.
3 + 2 x 12 = 27
The cost would be $27.
I believe that the answer to the equation is 10
