Question

a 4-ft wide painting should be centered on a 12 ft wide wall to the left side of the equation that can be determined how many feet should be on each side of the painting​

Answer 1

we need to add 4 ft of empty space on the left side of the painting to center it on the wall.

Explanation:

If the painting is 4 ft wide and the wall is 12 ft wide, then there will be 4 ft of painting and 8 ft of empty space on the left side of the painting, and 4 ft of painting and 8 ft of empty space on the right side of the painting.

To center the painting on the wall, we need to divide the empty space on the left and right sides equally. That is, we need to find half of the remaining space on each side of the painting.

Half of 8 ft is 4 ft, so there should be 4 ft of empty space on each side of the painting.

Therefore, we need to add 4 ft of empty space on the left side of the painting to center it on the wall.
