Answer:

9x - 9y + 8

Step-by-step explanation:

Simplify means to solve, but in this context it means to "shorten" it by adding the like terms together:

7x - 9y + 15 + 2x - 7

rearrange to make it easier, optional

7x + 2x - 9y + 15 - 7

add like terms

Sphere with diameter 1 unit is enclosed in a cube of side 1 unit each. find the unoccupied volume remaining inside the cube.
Ksivusya [100]
The volume of the sphere is given by:
 V1 = (4/3) * (pi) * (r ^ 3)
 Where,
 r: sphere radio
 Substituting values:
 V1 = (4/3) * (3.14) * ((1/2) ^ 3)
 V1 = 0.523 units ^ 3
 The volume of the cube is given by:
 V2 = L ^ 3
 Where,
 L: length of the sides
 Substituting values:
 V2 = 1 ^ 3
 V2 = 1 units ^ 3
 The unoccupied space is:
 V2-V1 = 1-0.523
 V2-V1 = 0.477 units ^ 3
 Answer:
 
The unoccupied volume remaining inside the cube is:
 
0.477 units ^ 3
