Question

Which of the expressions are equivalent to the one below? Check all that apply. (10 + 8) • 2

Answer 1

this is an exercise in distributive property and commutative property

distributive
a(b+c)=ab+ac
in this case
2(10+8)=(2*10)+(2*8)
so it is B

also commutative
a+b=b+a
(10+8)(2)=(8+10)(2)


So B and D are the correct answers

Answer 2

(10+8) =18
18×2=36

B and D are equivalent to (10+8) · 2
