Answer:
V = l×w×h units³
Step-by-step explanation:
The volume of a rectangular prism is V = l×w×h
Letter B is the answer
Number of sides (n) = 8
Apothem (a) = 18.11 units
Side (s) = 15 units
Area of Octagon = (1/2)n*a*s
A of O= (1/2)*8*18.11*15
A of O= 1086.6 units^2
Area of Square = s^2
A of S = 15^2
A of S = 225 units^2
Area of Shaded Region = A of O - A of S
A of S.R. = 1086.6 units^2 - 225 units^2
A of S.R. = 861.6 units^2
A of S.R. = 862 units^2
LETTER B
You must distribute first.
8 times (3x-2)= 24x-16
2 times (12x-5.5)= 24x-11
What you have left is
(24x-16)-(24x-11)
24x-24x=0
-16- -11=-5
The answer is -5
