Question

Given that ( AB = 3.2 + 4 ) and ( CD = 7 + 16 ), find the length of line segment ( AB ).

(A) ( 7.2 )
(B) ( 8.2 )
(C) ( 19 )
(D) ( 20 )

Answer 1

The length of the line segment AB is 7.2 units.

Step-by-step explanation:

The student's question asks to find the length of the line segment AB given that (AB = 3.2 + 4) and (CD = 7 + 16). To solve for AB, we simply need to perform the addition within the parentheses. Therefore, AB = 3.2 + 4 = 7.2. Since we only need to find the length of segment AB, the information about CD is not necessary for this problem.
