Answer:
Segment BF = 16 is true.
Step-by-step explanation:
Since, DE is parallel to BC, so DE will divide AB and AC proportionally.
Hence,

⇒
{Since, given that AE = 12, EC = 18 and AD = 6}
⇒ BD = 9.
Again, since, EF is parallel to AB, so EF will divide BC and AC proportionally.
Hence, 
⇒
{Since, given that AE = 12, EC = 18 and FC= 24}
⇒ BF = 16.
Therefore, segment BF = 16 is true. (Answer)
Yes because when you turn into a decimal it's 7.2
Cost of 6 sweets = 24p
so, cost of 1 sweet = 24p/6 = 4p
Now, cost of 5 sweets will be =4p*5 = 20p
complementary angles are angles that, when added together, make 90 degrees.
