Can someone answer the 3 questions that aren’t filled in ?

You had mistakes, so I did all of them.

9) -6(1 + 11b) = -6 - 66b

10) -10(a - 5) = -10a + 50

11) -3(1 + 2v) = -3 - 6v

12)-4(3x + 2) = -12x - 8

13) (3 - 7k)*-2 = -2 * (3 - 7k) = -6 + 14k

14) -20(8x + 20) = -160x - 400

15) (7 + 19b)*-15 = -15(7 + 19b) = -105 - 285b

16) (x + 1) * 14 = 14(x + 1) = 14x + 14

the answer for this question is 38
