Answer:
A: 2+27=29
B: The sum of the integers 2 and 27 is the integer 29, which demonstrates that integers are closed under addition.
Step-by-step explanation:
Since, closed property of addition for a set A is defined as,
∀ x, y ∈ A ⇒ x + y ∈ A,
∵ Set of integer is closed under multiplication,
If Z represents the set of integer,
Then 2, 27 ∈ Z ⇒ 2 + 27 = 29 ∈ Z,
Hence, the equation illustrates given statement,
2+27 = 29
The statement that correctly explains given statement,
The sum of the integers 2 and 27 is the integer 29, which demonstrates that integers are closed under addition.c

Answer:
108 cubes
Step-by-step explanation:
Lengths of one of the cube s=
Volume of a Cube 
Volume of one of the Cubes 
The volume of the rectangular prism is 4 cubic units.
Therefore, to find the number of cubes it takes to fill the prism, we divide the volume of the prism by the volume of the cube.

It takes 108 cubes to fill the rectangular prism.
Answer:
x=8
Step-by-step explanation:
3(x-5)=9
3x-15=9

3x=24
x=8
Answer:
Im pretty sure it is $660
Step-by-step explanation:
(25x9)+(15x8)+(23x15)=
225+120+345= 690
690-(6x5)
690-30
