X=21.6 I think is the answer if I did my math wrong
Answer:

Step-by-step explanation:

Suppose a generic quadratic equation

To factor this equation, I need to find its roots. Then we use the quadratic formula of:

and

So, for the equation 63x ^ 2-3x-6 we have:

and

So:

and

Finally the polynomial is:

Sqrt 64 is 8,
sqrt 81 is 9
sqrt 100 is 10,
sqrt 121 is 11,
sqrt 144 is 12,
sqrt 169 is 13,
and sqrt 196 is 14.
Answer:
Step-by-step explanation: equivalent means equal to, so that means these expressions are equal :)
N is the number
divided by 6 then n/6
5 was taken away so (n/6)-5
the result is multiplied by 2 so 2((n/6)-5)
result is -12
-12=2((n/6)-5)
divide both sides by 2
-6=(n/6)-5
add 5
-1=n/6
times 6
-6=n
da number was -6
