240 is the answer you're looking for!
Step-by-step explanation:
To find the area, spilt the trapezoid into 3 shapes.
2 triangles (at the ends) and 1 rectangle (the center).
Let's start with the rectangle, the formula for rectangle area is:
The length of the rectangle is 12, the width is 20. Add the numbers in:
Solve:
The area of the rectangle is 240. Now solve for the Triangles.
The formula for finding the area of triangles are is:
The length of the triangle is 12. To find the width subtract 20 from 30.
L = 12, W = 10. Add in the numbers.
Use order of operations to solve, start with parenthesis:
Rember to divide it by 2 because a triangle is half of a rectangle.
Since there are two identical triangles, you don't need to solve for the other
Now, add the areas together:
Then solve:
The correct answer is 240.
For this case, we find the equation of the line, for this we look for points where the line passes:
We found the slope:
Thus, the equation of the line is:
We substitute a point to find "b":
Finally:
Now, the domain is given by all the values for which the function is defined.
It is observed that "x" can take any value, that is, it is defined for all real numbers.
