Which one of the following pairs of expression are equal?

• A. 3 + 6, 2(2 + 3)
• B. 5 + 10, 3(2 + 3)
• C. 4 + 4, 2(1 + 4)
• D. 3(1 + 5), 3 + 9

Answer 1

The correct option is B 5 + 10, 3(2 + 3)

In the expressions, 5 + 10 and 3(2 + 3),

5 + 10 = 15

3(2 + 3) = 3(5) = 15

Therefore, the expressions
5 + 10, 3(2 + 3) are equal.
