Answer:
(3x + 1)²
Step-by-step explanation:
Given
9x² + 6x + 1 ← is a perfect square of the form
(ax + b)² = a²x² + 2abx + b²
Compare like terms to find a and b
a²x² = 9x² ⇒ a² = 9 ⇒ a = 
= 3
b² = 1 ⇒ b = 
= 1
and 2ab = 2 × 3 × 1 = 6
Thus
9x² + 6x + 1 = (3x + 1)²
Answer: the amount a person pays for gas compared with the number of gallons purchased
Step-by-step explanation:
(6x–1)(6x+1) - 4x(9x+2) = −1
Simplify the left side:
36x^2-1 -36x^2-8x = -1
Combine like terms:
-1 -8x = -1
Add 1 to both sides:
-8x = 0
Divide both sides by -8:
x = 0 / -8
x = 0
The root is 0
<span>Outcome Heads Tails
Relative Frequency 0.69 0.31
so first statement is false as 69% is close to 70%.
second statement is false as heads probability is close to 70%
last 2 statements are true:
</span><span>The theoretical probability of tails is most likely 30%.
It is likely that the coin is not fair.

Pi•r^2
Radius= 15
Plug in and that should give you the blue area. =706.858
If you added 3 feet to the circle that would change the radius to 18 so back to the formula...
Pi•18^2
=1,017.876
To find the shades you would have to subtract the two and get your answer
Interesting. Either the answer choices are wrong or I am.... is the formula right? Lol it’s been too long
