A).5(20+4)5(20+4)
B).2(98+10)2(98+10)
C).10(10+2)10(10+2)
D).2(50+10)2(50+10)

Answer 1

The expression that is NOT equivalent to 100+20,100+20 is B) 2(98+10)2(98+10), which simplifies to 216.

Step-by-step explanation:

To determine which expression is NOT equivalent to 100+20,100+20, we can simplify each expression and compare the results.

A) 5(20+4)5(20+4) = 5(24) = 120

B) 2(98+10)2(98+10) = 2(108) = 216

C) 10(10+2)10(10+2) = 10(12) = 120

D) 2(50+10)2(50+10) = 2(60) = 120

The expression that is NOT equivalent to 100+20,100+20 is B) 2(98+10)2(98+10), which simplifies to 216. Therefore, the correct answer is B).
