6(x+2) = 6x + 12
3(x-9) = 3x - 27

6x + 12 + 3x - 27 = 9x - 15

6(x + 2) + 3(x - 9)

6(x + 2) = 6 * x = 6x , 6 * 2 = 12
6x + 12

3(x - 9)= 3 * x = 3x , 3 * -9 = -27
3x - 27

6x + 12 + 3x - 27=

6x + 3x = 9x
12 - 27 = -15

Answer: 9x - 15

How many unit cubes would it take to completely fill the prism with no gaps between unit cubes?
Lemur [1.5K]

Answer:

72 cubes

Step-by-step explanation:

Top view of the rectangular prism shows the unit cubes arranged in two rows along the length.

In each row number of unit cubes arranged = 9

Right view side of the prism shows the unit cubes arranged in two columns.

Number of unit cubes in each column = 4

Total number of cubes arranged in the prism = (Number of cubes in each row × Number of cubes arranged in two columns) × Number of columns

= (9 × 4) × 2

= 72

Therefore, number of cubes filled completely in the prism with no gaps = 72
