Answer: 
Step-by-step explanation:
You need to use the following formula that is used to find the area of a trapezoid:

Where "M"and "m" are the bases of the trapezoid and "h" is the height of the trapezoid.
Based on the information given in the exercise, you can identify that:

Knowing these values, you can substitute them into the formula:

Finally, you must evaluate in order to find its area. This is:

Answer:
The answer is x=12.
Step-by-step explanation:
First, to solve this equation you need to isolate the x variable. To isolate the variable, you must, subtract the other term from both sides. Subtracting 18 from both sides, you are left with 3x = 36. Since 3 times x = 36, dividing both sides by 3 gets you, x=12.
