Answer:

See a solution process below:

Explanation:

To use the distributive property, first rewrite the term within the parenthesis as:

#(4 + 2/7)21#

Next, multiply each term within the parenthesis by the term outside the parenthesis:

#(4 + 2/7)color(red)(21) =>#

#(4 xx color(red)(21)) + (2/7 xx color(red)(21)) =>#

#84 + (2/color(red)(cancel(color(black)(7))) xx cancel(color(red)(21))3) =>#

#84 + 6 =>#

#90#
