## anonymous one year ago I GIVE MEDAL TO PEOPLE WHO HELPED ME Identify the property shown. (7 • p) • 2k = 7 • (p • 2k) A. distributive B. associative C. commutative D. transitive

distributive is when a ( b + c ) = a*b + a*c associative is when a + ( b + c ) = ( a + b ) + c [moving the parenthesis around] commutative is when a + b + c = a + c + b [switching the numbers into a different place] transitive is when if a = b and b = c , then a = c

:D thx

wait im still confused

what do you think your example is doing? (7 • p) • 2k = 7 • (p • 2k) hint: (a + b) + c = a + (b + c)

which option does it look like? :)

6. anonymous

is it A?

not quite :) that would have looked like (7 • p) • 2k = 14k * 2pk ^^^ which is not what happened ;P

8. anonymous

B ?

that's right! ^_^

yay

hint: associative property with respect to the multiplication, is: $\Large \left( {a \cdot b} \right) \cdot c = a \cdot \left( {b \cdot c} \right)$
