A is the correct answer.

  1. 2x+4=4x-2
  2. 2x+4+2=4x-2+2
  3. 2x+6=4x
  4. 2x-2x+6=4x-2x
  5. 6/2=2x/2
  6. 3=x

<span>The correct answer is A, as you add two to both sides, giving 2x +6=4x, then subtract 2x from both sides, giving 6=2x, and then divide both sides by 2, giving 3=x.</span>

I NEED HELPPP<br><br> Whats the length of LN?
andre [41]

Answer:

LN = 66 cm

Step-by-step explanation:

The 3 parallel lines divide the 2 sides they intersect in proportion, that is

\frac{DE}{EF} = \frac{LM}{MN} , substitute values

\frac{7}{15} = \frac{LM}{45} ( cross- multiply )

15LM = 315 ( divide both sides by 15 )

LM = 21

Hence

LN = LM + MN =  21 + 45 = 66 cm

The two triangles are similar.
igor_vitrenko [27]

Answer:

  • x = 10

Step-by-step explanation:

<u>The ratio of corresponding sides of similar figures is same:</u>

  • 3x/20 = (4x + 2)/(20 + 8)
  • 3x/20 = (2x + 1) / 14
  • 3x(14) = (2x + 1)(20)
  • 42x = 40x + 20
  • 2x = 20
  • x = 10
