#-8 + 40x#

Explanation:

The parentheses tell us that we multiply all the terms by the outside factor.

So #-8(1-5x)# is really #-8 xx 1 - (-8 xx 5x)#

NOTICE how I put the "stuff" after the subtraction sign into parentheses. That's because we need to simplify #-8# and #5x# before we subtract it

#-8 - (-40 x)#

#-8 + 40x#
