3x^2-12x+1=0
Use formula to solve quadratic eqns
Standard form of quadratic eq is ax^2+bx+c
-b(+,-)sqrtb^2-4ac/2a
Now can u find x?
The angles in the other quadrilaterals that are congruent to angle C are: b. angle E and angle K.
<h3>What are Congruent Quadrilaterals?</h3>
Congruent quadrilaterals are quadrilaterals that have corresponding sides that are congruent and also corresponding angles that are congruent and equal to each other.
If two or more quadrilaterals are congruent, they have the same shape and size.
Given that the three quadrilaterals in the image are congruent to each other, all their corresponding angles would also have the same angle measures.
Angle C in quadrilateral ABCDE corresponds to angles E and K in the other two quadrilaterals. Therefore, the angles in the other quadrilaterals that are congruent to angle C are: b. angle E and angle K.

<span>multiply the first equation by 5 and 2nd by -7 and you get
35x-30y=-5
-35x+28y=-7
now you can cancel out the x's and you get
-2y=-12
so
y=6
now you can just plug y=6 into one of the original equations and you will see that x turns out to be 5
Hope thats okay</span>
Answer:
Connect the two centers to produce the trend line
Step-by-step explanation:
When the dots have been plotted, there are three steps to find the trend line on a scatter plot:
1. Draw a vertical line that separates the full set of points into two sets, each with the same number of dots.
2.Mark with a special sign (e.g + or ×) the middle value in each of the two sets obtained in the previous step.
3.Join the two marks mentioned in the step (2) with a straight line, and extend it to the edges of the graph. This line is the trend line, and this is the last step.
Thus, the last step when using the divide-center method to find the line on scatter plot is Connect the two centers to produce the trend line.
