And the conversion for the inch to the centimeter is 1 inch = 2.54 cm exactly. So, in the same vCalc conversion equation (Length Conversion), if you input 1 inch, you get out 2.54 cm. So, he rephrased answer to your question is: there are 30.48 centimeters on a standard 12 inch ruler.
f(x)= x^2 -6x +21
0 =x^2-6x+21
subtract 21 from each side to prepare for completing the square
-21 = x^2 -6x
completing the square (b/2)^2
(-6/2) ^ =3^2 = 9
add 9 to each side
-21 +9 = x^2 - 6x + 9
-21 +9 =(x-3) ^2
-12 = (x-3)^2
take the square root of each side
+- sqrt(-12) = x-3
add 3 to each side, take out the negative inside the square root
3 +- i sqrt(12)=x
simplify the square root sqrt(12)= sqrt(4)sqrt(3) =2sqrt(3)
3 +- i 2sqrt (3) = x
Answer: 3+2isqrt(3)
3-2isqrt(3)
Answer:

Step-by-step explanation:

Answer by JKismyhusbandbae: 16.2
All you do is add the same number every-time.
2.7 + 2.7 to get 5.4.
8.1 + 8.1 to get 16.2
If you wanted to find y again 5.4 + 5.4 = 10.8.
