The constant that can be added to 
- 3x to form a perfect square trinomial is 
The given expression is
- 3x
To form a perfect square trinomial
The given expression is
- 3x
first we have to add a constant term with it
- 3x + z
By comparing the given expression and the perfect square trinomial
a = x
Similarly
-2ab = 3x
where know a =x
Then,
-2b = 3
b = -3/2
Similarly
= z
9/4 = z
Convert the simple fraction to mixed fraction
9/4 =
Hence, the constant that can be added to - 3x to form a perfect square trinomial is

Answer:
slope is 10
y-intercept is 18
Step-by-step explanation:
Answer: 
Step-by-step explanation:
Given, the length of the rectangular dog run is 18 feet.
Formula: Perimeter = 2 ( length + width)
Let width be x.
Then, Perimeter = 2 (18 + x ) feet
The perimeter of the dog run must be at least 42 feet and no more than 72 feet.
That is
Divide inequality by 2, we get
Subtract 18 from each side, we get
Required inequality :
Answer:
R = 450%/year
Equation:
r = (1/t)(A/P - 1)
Converting r decimal to R a percentage
R = 4.5 * 100 = 450%/year
Do you mean like this?
Y = -x - 4
Y = x
x = -x - 4
2x = -4
x = -2
Therefore y = -2
