Answer:
Step-by-step explanation:
To complete the square you need to add to both sides. (Parenthesis around b/2)
b = 10
b/2 = 5
(b/2)^2 = 25
+10x + 16 = 0
subtract 16 to both sides
+ 10x = -16
add 25 to both sides
+10x + 25 = 9

Total area = 12 + 18 = 30cm²
That the variable Z is directly proportional to X and inversely proportional to Y means Z = A (X/Y)
=> A = Z* Y / X
=> 9.5 * 6 / 3 = Z * 12 /8
=> Z = 9.5 * 8 * 6 / (3 * 12) = 12.67
Answer: 12.67
