Find the area of the triangles, multiply that value by 4. Then add that sum to the surface area of the base. The total surface area is equal to 28.
The answer to the problem is x=2
3x-x+2=4, That should be your answer if that is what your looking for
Step-by-step explanation:
3x-47=65
3x=65+47
3x=112
x=37.3
the answer is $19,because you add the cost of 2 adult tickets 18$ and the cost of 1 student ticket 3$ and get 19$
