Answer:
AB + BC + CD = AD
Therefore, 4x + 1 = 19
Step-by-step explanation:
The total length of the line (AD) is a sum of line AB, line BC, and line CD
AD = AB + BC + CD
19 = x + x+1 + 2x
4x + 1 = 19
Answer/Step-by-step Explanation:
I think the equation is true because AD = AB + BC + CD ,which represents the equation given
