Collect like terms:
You have 2 with mn so 9mn - 9mn =0
You also have 2 with m4n so -19m4n - 12m4n = -31m4n
Put it together:
-31m4n -8m2
So C

Which of the following congruence statements are correct?
solong [7]
Only B and F are true. The letters are set up so the parts that you choose must have the letters in the same place on each triangle.

So if ABC is a triangle congruent to PQR
Then AB is congruent to PQ because AB are the first 2 letters of ABC and PQ are the first 2 letters of PQR.
AC is congruent to PR (why?)

Help i really have no clue not sure where to start
Juli2301 [7.4K]

Focus on the top line angles for now.

Those two angles combine to the straight angle ABC, which is 180 degrees.

(angleABY) + (angleYBC) = angle ABC

(x+25)+(2x+50) = 180

(x+2x) + (25+50) = 180

3x+75 = 180

3x = 180-75

3x = 105

x = 105/3

x = 35

We'll use this x value to find that:

  • angle YBC = 2x+50 = 2*35+50 = 70+50 = 120 degrees
  • angle BEF = 5x-55 = 5*35-55 = 175-55 = 120 degrees

Angles YBC and BEF are corresponding angles (they are both in the northeast corner of their respective four-corner angle configuration). They are both 120 degrees. Since we have congruent corresponding angles, we have effectively proven that AC is parallel to DF. Refer to the converse of the corresponding angles theorem.

The regular version of the "corresponding angles theorem" says that if two lines are parallel, then the corresponding angles are congruent. The converse reverses the logic of the conditional statement. Meaning that if the corresponding angles are congruent, then the lines are parallel.

Well since there are 4 values calculated then 2 would be above the  mean because plus the 2 values above the mean. I don't know if it makes since though.
