Determine the valeur for k in the equation below:

x2 + kx + 9 = 0

Step-by-step explanation:

Disc.=k²-4×9

roots are real if k²-36≥0

|k|≥ 6

k≤- 6

or k≥ 6

roots are imaginary if k²-36≤0

k²≤ 36

|k|≤6

roots are imaginary if -6 ≤ k ≤6

the forst and 3rd

image result for what is another name for consecutive interior angles? ​

when two lines are crossed by another line (called the transversal): the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles. in this example, these are consecutive interior angles: d and f.
