Answer :
-9 (z+3) -5 (2z+10) = -9z - 27 - 10z - 50 = -9z - 10z - 27 - 50 = -19z - 77 ;
-9(z + 3) - 5(2z + 10)
Distribute -9:
-9z - 27 - 5(2z + 10)
Distribute -5:
-9z - 27 - 10z - 50
Combine like terms:
-19z - 77
Distribute -9:
-9z - 27 - 5(2z + 10)
Distribute -5:
-9z - 27 - 10z - 50
Combine like terms:
-19z - 77
