Answer:
C
Step-by-step explanation:
C is the answer hope you mark me brainlyist
X^2 + 4x + 4 = (x + 2)^2
so the answer is 4.
Add 12 to both sides
6x^2 = -1 + 12
Simplify -1 + 12 to 11
6x^2 = 11
Divide both sides by 6
x^2 = 11/6
Take the square root of both sides
x = ±√11/6
Simplify √11/6 to √11/√6
<em>x = ±11/√6</em>
<u>Answer: B) x = ±11/√6</u>
Step-by-step explanation:
Answer:
2:13
Step-by-step explanation:
The ratio of;
20 gallons to 130 gallons
20:130
Dividing by 10 on both sides gives:
2:13
You can't simplify it further and so its the answer.
