Equivalent Expressions Using the Distributive Property. 3 (5). = 5 + 5 + 5. 2 ( 4 + 6). =( 4 + 6 ) + ( 4 + 6). = 4+6+4+6. = 4+4+6+6. = 2(4) + 2(6). 2 ( 4 + 6 ) = 2(4) + 2(6). 4 ( m + n). =( m + n ) + ( m + n ) + ( m + n ) + ( m + n ). = m + m + m + m + n + n + n + n.
E N D
3 (5) = 5 + 5 + 5
=( 4 + 6) + ( 4 + 6) = 4+6+4+6 = 4+4+6+6 = 2(4) + 2(6)
2 ( 4 + 6) = 2(4) + 2(6)
=( m + n) + ( m + n) + ( m + n) + ( m + n) =m+m+m+m+n+n+n+n = 4m + 4n
4 ( m + n) = 4m + 4n
Let’s Try It! Write an equivalent expression using the distributive property.
Let’s reverse it… 7∙3 + 7∙8 = 7(3+8)
10c + 10d = 10(c+d)
Try It! 8(6) + 8(7)
