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.
Answer:
Step-by-step explanation:
hello :
1) the system is : y=5x+4
y = 2x+1
so :5x+4 =2x+1
5x-2x=1-4
3x= -3 so : x= -1 but y =2x+1 put x=-1 you have : y =-1
the solution : (x,y) =( -1, -1)
2) the system is : x + y = 4
4x -y = 1
means : y = - x+4 (line red)
y= 4x-1 (line blue)
graficly : intrsection is : (x,y) =(1 ,3 )
Answer:
Step-by-step explanation:
By definition, similar polygons have corresponding sides in a constant proportion. Therefore, we can set up the following proportion (ratio of corresponding sides) to solve for :
