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
Which expression is equal to (21)(7)(3x) using the associative property?

(21 · 7 · 3)x


(7)(21)(3x)

32(7 + 3x)

(3x)(7)(21)
Use the distributive property to rewrite the expression 8(–2x – 3).

–16x – 3

–16x + 3

–16x – 24

–16x + 24

Answer 7

@BAdhi

Answer 8

commutative means if there is,
(p+q+...)(c+d+...) -> we can write as (c+d+..)(p+q+...)

for example

(5+7)(3+4) is same as (3+4)(5+7) from the commutative property

remember after application of any of these properties you should get the same result as the the expression that you began with

so if we take your answer it give two different answers (3 + 7)(-2) = -20 where as 3(7 – 2) = 15

Answer 9

so its A

Answer 10

You have to use the distributive property.

Answer 11

@BAdhi is my answer for the third one correct?

Answer 12

yes

assosiative property means

\((a\times b)\times (c) = (a)\times(b\times c) = (a\times b\times c)\)
