9. Stephanie had some candy to give to her four children. She first took twelve pieces for herself and then evenly divided the rest among
her children. Each child received six pieces. With how many pieces did
she start?

36 pieces

Step-by-step explanation:

We know she took 12 pieces and her four children each received 6 pieces.

12 + 4 (6) = p

12 + 24 = 36

p = 36

She started with 36 pieces.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
