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.
You can clear the zeros in the equation from the exponents. after you factor it should be
Answer:
y=1/3-5/3
Step-by-step explanation:
13. Picture is cut off. Insufficient information is shown.
14. ST = 2×(XY)
8z +3 = 2(3z +2)
2z = 1
z = 1/2
Answer:
Farthest left 1 1/3
Step-by-step explanation:
5-4 = 1
Since the denominators are the same, subtract 2 and 1
