Answer: D
Step-by-step explanation: To find the area of a triangle, you multiply the base and the height, then divide by 2, but because there are 4 triangles, you can multiply 12 and 14, and then multiply again by 2. For the square, 12 times 12 is 144, when you add 336 (the area of the triangles) and 144 (the area of the square), you get 480.
Divide 0.13 by 0.25 and your answer should be 0.52.
That would be the slope of this straight line; it's 30 units / lesson, e. g., $30/lesson. The $25 is the registration and/or up-front cost.
