Step-by-step explanation:
Perfect square trinomial:
A perfect square trinomial has the following format:

a.
x² – 8x

So 2a = 8, a = 4. Then

The perfect square trinomial is 
b. x2 + 20x +
2a = 20, so a = 10

The perfect square trinomial is 
C.
x² – 16x +
2a = -16, so a = -8.

The perfect square trinomial is 
d. x2 + 9x +
, so 

The perfect square trinomial is

Answer:
Step-by-step explanation:

Answer:
There is no solution.
Rewrite -2x + y = -6 so it starts with y =...
y = 2x - 6
Substitute that in 2/3x - 1/3y = -2 gives:
2/3x - 1/3*(2x -6) = -2
2/3x - 2/3x + 2 = -2
0 + 2 = -2
This statement is not true, and that means there is no solution.
