Question

(a) show that 4x+1=19​

Answer 1



Answer/Step-by-step Explanation:

I think the equation is true because AD = AB + BC + CD ,which represents the equation given

Answer 2

AB + BC + CD = AD

Therefore, 4x + 1 = 19

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
