Answer:

18 inches

Step-by-step explanation:

We are given that Mark wants to hang four rectangular pictures in a row on a wall so that the horizontal space between each picture is always same.

Length of  each picture=8 inches

Length of wall=74 inches

Horizontal space before first picture and after the fourth picture=12 inches

We have to find space between pictures.

Let x be the space between pictures

\(12+12+8+8+8+8+x=74\)

\(x+56=74\)

\(x=74-56=18\)

Hence, the distance between pictures=18 inches
