Last one:
x^3-2^9=
(x-8)(x^2+64+8x)
10' x 12' are the dimensions for the floor and roof, both of which will not be covered with wallpaper.
The room will have two identical walls with the following dimensions:
10 x 8
12 x 8
The total area to be covered is:
2 x 10 x 8 + 2 x 12 x 8
Total area = 352 square feet

A dozen of doughnuts cost $5 and a dozen of croissants cost $6.
Step-by-step explanation:
Let,
Cost of 1 dozen doughnuts = x
Cost of 1 dozen croissants = y
According to given statement;
7x+3y = 53 Eqn 1
x+5y = 35 Eqn 2
Multiplying Eqn 2 by 7
Subtracting Eqn 1 from Eqn 3
Dividing both sides by 32
Putting y=6 in Eqn 2
A dozen of doughnuts cost $5 and a dozen of croissants cost $6.
