Answer:
18cm
Step-by-step explanation:
presents=x
14cm=7x
divide by 7
2=x
find 9x
9*2=18
Step-by-step explanation:
f(x) = x² + 6x + 12
= (x² + 6x + 9) + 3
= (x + 3)² + 3.
Since a² >= 0 for all real values of a,
(x + 3)² >= 0 for all real values of x,
(x + 3)² + 3 >= 3 for all real values of x.
Hence f(x) >= 3. (Shown)
