A side of an equilateral triangle is 24 inches. The midpoints of its sides are joined to form an inscribed equilateral triangle. If this process is continued without end, find the number of inches in the sum of the lengths of the altitudes of all of these triangles.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
