Final answer:
To form 5 hexagons using pattern block trapezoids, 30 trapezoids are needed because each hexagon is made up of 6 trapezoids.
Step-by-step explanation:
The question asks how many pattern block trapezoids would create 5 hexagons. To solve this, we need to know the relationship between the trapezoids and the hexagons. A single hexagon can be created by arranging 6 trapezoids with their shorter bases adjoining the sides of the hexagon. Therefore, to create 5 hexagons, we would need 6 trapezoids per hexagon, which results in a total of 30 trapezoids.
