If you guys can answer this 3 questions right , I’ll mark brainlest

64, -28, 16

Step-by-step explanation:

Q5

j - h(j - h),  if j = 4, h = -6

4 - (-6)(4 - (-6)) =4 + 6(4 + 6) =4 + 6(10) =4 + 60 =64Q6

y(5 - (6 - z)), if y = 4, z = -6

4(5 - (6 - (-6)) =4(5 - (6 + 6)) =4(5 - 12) =4( - 7) =-28Q7

x(h - x/2) + h, if x = 2, h = 6

2(6 - 2/2) + 6 =2(6 - 1) + 6 =2(5) + 6 =10 + 6 =16

How am i goonna know explain
