This equation is not factor-able, so we can use the quadratic formula.
x=(-11+square root(11^2-4(-12*-3)))/(2*-12)
x=(-11+square root(-23))/(-24)
Since we have the square root of a negative in this equation, there are no real roots for the quadratic.
The correct answers are, <u><em>A, D, and E.</em></u>
The correct option is : no mode
<u><em>Explanation</em></u>
The given data set is: 
The <u>mode is the number that is repeated more often</u> than any other number in the data set.
But here we can see that all the numbers in this data set are different. That means <u>they appear only once</u>.
So, there will be 'no mode' in this set.
The angles must be opposite to be equal to each other so parallelogram ABCD
Line AB is parallel to DC and line AD is parallel to BC
C is the correct answer
It is 84 ibs
Explanation
It’s actually easy if you learn 5 minutes of it
But thats the correct answer
