If you expand this equation first
You get -4u+6+3u=3u+24

And if you simplify that you get:
-u+6=3u+24
Now you need to solve this equation to find u

First bring 3u to the other side to -u-3u (the positive changes to negative)
Now the equation is
-4u+6= 24
Take 6 of both sides
-4u=24-6= 18
-4u= 18
So u= -18/4
Which simplifies to -9/2

Answer: -9/2

PLEASE ANSWER !!! NEED DONE ASAP

Only the triangles in figures <u>5 are congruent</u>

<h3>Further explanation </h3>

Triangles are said to be congruent if:

  • 1. all three sides equal (SSS ---> side, side, side)
  • 2. two sides and the included angle of 2 triangles, are equal (SAS -> Side, Angle, Side)
  • 3. If the two angles and the included sides of the 2 triangles are equal (ASA -> Angle, Side, Angle)
  • 4. If the two angles and the non-included sides of 2 triangles are equal (AAS -> Angle, Angle, Side)

1. △ABC ≠ △DCE : not congruent

at least 3 parts (sides or angles) are compared, in the picture only 2 sides are compared

2. △ABC ≠ △XYZ : not congruent

the angles not includes between two sides

3. △RST ≠ △VUT : not congruent

a minimum of 3 parts (sides or angles) are compared, in the picture only 1 angle and 1 side are compared

4. △DEF ≠ △DHG :  not congruent

at least 3 parts (sides or angles) are compared, in the picture only 2 sides are compared

5. △JKL ≅ △KJM : congruent with ASA theorem

uysha [10]

Well, the number should be 2,222 since she wants the hundreds place to be a 2, being worth 200. Since she wanted all the digits to have the same number, it would be 2,222 for your final answer.

Hope this helped!
