7. You are finding the area of the box. Not the cube, just a surface. Length times width of the surface. Eliminate other numbers and multiply
24.5×19.5
then
26×24.5
8. You are doing the same thing almost. Word problems are scary, but look for the numbers.
4inch ×8inch × 12inch
Find the volume
Multiply the volume by 3, that'd one answer 
Devide the ORIGINAL volume by 2. don't divide the volume you multiplied by 3.
        
             
        
        
        
The coordinates of the image point are given to be B(4, -8). We are to find the coordinates of pre-image that is the coordinates before the translation.
The translation made was (x-2, y+3) 
This means, the x coordinate was moved 2 units to left and y coordinate was moved 3 units above. 
So, the coordinates of original point will be, 2 units to right of B and 3 units down of B.
So the coordinates will be (6, -11)

Answer:
x = -119/3 = -39 2/3
Step-by-step explanation:
(128 +7x- 12) = (4x - 3)
Combine like terms
(116 +7x) = (4x - 3)
Subtract 4x from each side
116 +7x-4x=4x-4x-3
116 +3x = -3
Subtract 116 from each side
116-116 +3x = -3-116
3x = -119
Divide each side by 3
3x/3 = -119/3
x = -119/3
x = -39  2/3
 
        
             
        
        
        
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
