Answer:
A) x = ±2i√3
Step-by-step explanation:
We presume you want to find x such that f(x) = 0.
Divide by 13:
x² + 12 = 0
Subtract 12:
x² = -12
Take the square root:
x = ±i√12 = ±2i√3
For example, three points are always coplanar, and if the points are distinct and non-collinear, the plane they determine is unique. However, a set of four or more distinct points will, in general, not lie in a single plane. Two lines in three-dimensional space are coplanar if there is a plane that includes them both.
Answer:
Step-by-step explanation:
The slopes of the two lines (representing the speeds of the trains) are the same, and so the two trains are traveling at the same speed.
The answer is going to be C
Answer: Same-Side Interior Angles Theorem
Step-by-step explanation:
- Same-Side Interior Angles Theorem says that when two lines are parallel and a transversal intersects it , then the angles on the same interior side are supplementary.
We are given that Two parallel lines PQ and RS are drawn with KL as a transversal intersecting PQ at point M and RS at point N.
Angle QMN is shown congruent to angle LNS.
Also, angle QML and angle SNK are the angles lies on the same side of the transversal.
It means the measure of angle QML is supplementary to the measure of angle SNK [ By Same-Side Interior Angles Theorem ]
