Question

23. Which expression is NOT equivalent
to the expression 38 – 14?
A 2(19-7)
B 24
C (19-7)2
D 2(36-12)

Answers

  1. Answer: [D] 2(36-12)
    Step-by-step explanation:
        First, we will simplify the given expression.
    38 – 14 = 24
        Now, we will see if the other expressions are equivalent or not.
    [A] 2(19-7) = 24
    [B] 24 = 24
    [C] (19-7)2 = 24
    [D] 2(36-12) = 48
        The expression is NOT equivalent to the expression 38 – 14 is;
                       [D] 2(36-12)

  2. Hi 🙂
    Let’s evaluate all these expressions

    ———————

    \boldsymbol{\boxed{38-14=24}}}
      So Now the question boils down to —
    What expression is NOT equivalent to \boldsymbol{24?}
    • Option (A).
         \boldsymbol{2(19-7)}
         \boldsymbol{2(12)}
         \boldsymbol{24}
    Option (A) is ruled out, because we’re looking for expressions that are not equivalent to 24.
    • Option (B)
       Well 24 is always equal to 24!
    • Option (C)
         \boldsymbol{(19-7)2}
         \boldsymbol{(12)2}
         \boldsymbol{24}
    • Option (D)
        \boldsymbol{2(36-12)}
         \boldsymbol{2(24)}
         \boldsymbol{48}
