5x-2[5(x+2)-(x-5)]-6

Distribute

= 5x+ ( -2)(5(x+2))+( -2)( -x) + ( -2)(5) + -6

= 5x+ - 10x + -20 + 2x + -10 + -6

Combine like terms

= (5x+ -10x + 2x) + ( -20 + - 10 + -6)

= - 3x - 36

6m + 9m + 5. Then evaluate the expression for m = (-1)

(6)( -1) + (9)( -1) + 5

= -6 + (9) ( -1) + 5

= -6+ - 9 + 5

= - 15 + 5

= - 10
