A is the correct answer.

2x+4=4x-2
2x+4+2=4x-2+2
2x+6=4x
2x-2x+6=4x-2x
6/2=2x/2
3=x

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.

I NEED HELPPP 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:

The ratio of corresponding sides of similar figures is same:

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