Answer:
regular polygon of 9 sides has 9 lines of symmetry
Volume = = 138⁶/32 cubic meters
Step-by-step explanation:
Given:
Length = 8⅜ m
Width = 2 m
Height = 8¼ m
Required:
Volume as a mixed number
Solution:
Volume of rectangular prism = L*W*H
Plug in the values
V = 8⅜ × 2 × 8¼
Change to improper fraction
V = 67/8 × 2 × 33/4
= (67 × 2 × 33)/(8 × 4)
= 4,422/32
= 138⁶/32 m³
6r + 10
Explanation:
2(5 + 3r)
= (2)(5 + 3r)
= (2)(5) + (2)(3r)
= 10 + 6r
= 6r + 10
