Add C to both sides:

36 ×

Since 9 is a factor of 36 you can reduce the 36 to 4 and the 9 to one
Then just multiply what is left
4 <span>× 2 = 8
So, Mark completed 8 passes.</span>
Answer:

Step-by-step explanation:
The area
of a triangle is equal to half the product of its length (L) because of its height (h).

The base of the triangles is 
The height of the triangles is 
Then the area of one of the triangles is:

The figure is formed by 12 equal triangles, then the area of the figure
is:

Answer: H
