Answer:
|x - 34| = 4
Step-by-step explanation:
Minimum height of handrail stated by the safety regulation = 30 inches
Maximum height of handrail stated by the safety regulation = 38 inches
Mean of these heights = [tex]\frac{38+30}{2}=34[/tex]
If a handrail having height = x
Then the difference between height of the handrail and mean height = (x - 34)
This difference should be equal to 4.
Algebraic representation for a height "x inches" will be
|x - 34| = 4
