Please help with the attached problem “Solve the differential equation.” Thanks a lot!

The width of a rectangle is 20 units. can the perimeter p of the rectangle be 64 units when its length x is 11 units? no, because p = 2x + 2(20) no, because p ≠ 2x + 2(20) yes, because p ≠ 2x + 2(20) yes, because p = 2x + 2(20)

What is the missing reason in the proof? segment addition congruent segments theorem transitive property of equality subtraction property of equality?
