Respuesta :

8(C + 10) + 20

8C + 80                                (distribute 8 into everything inside the parenthesis)
8C + 80 + 20                        (drop down the 20 from the expression)
8C + 100                              (Simplify)
8C + 100                              (Your answer)

B is the correct answer

hope this helps
(8)(c) + (8)(10) + 20
= 8c + 80 + 20
= (8c) + (80+20)
= 8c+100
