Answer:
Millie is 11. Molly is 8.
Step-by-step explanation:
Step 1: Subtract 3 from 19. The reason why you do this is to make sure that you don't have an extra 3 lying in there for the next few steps.
19-3=16
Step 2: Divide 2 from 16. You do this because there are two sisters.
16÷2=8
8 will then become Molly's age
Step 3: Add 3 to 8. This will give you Millie's age because she is 3 years older than Molly.
3+8=11
In conclusion, Millie is 11 and Molly is 8.
Answer:
Option C - Perfect square trinomial.
Step-by-step explanation:
Given : Polynomial 
To find : What pattern is represented by the polynomial?
Solution :
First we make the polynomial in factor form,
Polynomial 
Since, it is not factor clearly so try to make the square.
Taking 4 common,

Identifying the x and y terms in the identity,

Factor the perfect square trinomial,
Therefore, The pattern polynomial represent is perfect square trinomial.
So, Option C is correct.
