Final answer:
The question is about finding the value of x for a line segment that is 21 ft long, with parts PQ and RQ labeled as 2x and 3x + 1 respectively. By setting up an equation and solving for x, we find that the value of x is 4.
Step-by-step explanation:
The student is asking about the value of x for a line segment of length 21 ft, where one part of the segment PQ is described as 2x and the other part RQ as 3x + 1. To find the value of x, we set up the equation:
2x + 3x + 1 = 21
Combining like terms, we get:
5x + 1 = 21
Subtracting 1 from both sides, we have:
5x = 20
Dividing both sides by 5 gives us:
x = 4
Therefore, the value of x is 4.
