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

7(2x - 3) = 1...distribute through the parenthesis
14x - 21 = 1.....step 1
14x = 22...step 2
x = 22/14 = 11/7 or 1 4/7
Answer:
pretty sure it's the 4th one
Step-by-step explanation:
the answer is x>-6
so x is greater than negative 6
