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

    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

    You have to use the distributive property.

    yes assosiative property means \((a\times b)\times (c) = (a)\times(b\times c) = (a\times b\times c)\)
