a = 73
b = 4
c = 0
d =
e = 39
f = 93
g = * 17 * 32
h = 8 + 32 + 66 * 5
Step-by-step explanation:
Q h is wrong so it could be 66 (40+5) = (66 * 40) + (66*5)
This is Distributive Property
The explanation for h is 66 (40+5) as per your question
could be like 40 = 32 + 8 ( 32 is mentioned in Question) therefore it would be 66 * 8 + 66 * 32 + 66 * 5
