Question

According to the commutative property of multiplication, which expression is equivalent to (3 + 7)(-2)?

-2(3 + 7)

3(7 – 2)

(3 + 7)(-2)

3 + 7 – 2

Answer 1

Option A is correct

`(-2)(3+7)`

Explanation:

Commutative property of multiplication states that any two numbers multiplied in either order i.e

`a \cdot b = b \cdot a`

As per the statement:

Given the expression:

`(3+7)(-2)`

Apply the commutative property of multiplication:

`(-2)(3+7)`

Therefore, (-2)(3 + 7) is the expression equivalent to
`(3+7)(-2)`

Answer 2

According to the commutative property of multiplication which has form


`a\cdot b=b\cdot a`,
you have

`(3+7)(-2)=(-2)(3+7)=-2(3+7)`.
The correct choice is A.
