Use the distributive property to expand this expression. See details below

Explanation:

For the distributive property we will multiply #color(red)(8)# by each term within the parenthesis:

#(color(red)(8) xx -10x) + (color(red)(8) xx 3.5y) + (color(red)(8) xx -7)#

#-80x + 28y + (-56)#

#-80x + 28y - 56#
