Answer:

1). x = 0

2). Option 3

Explanation:

1). If the two triangles are similar,

Their corresponding sides will be proportional.


(5x+2)/(6)=(x+4)/(12)

12(5x + 2) = 6(x + 4)

60x + 24 = 6x + 24

60x - 6x = 24 - 24

54x = 0

x = 0

2). Option 1

2(x - 6) + 3 - 5x = -3x - 9

2x - 12 + 3 - 5x = -3x - 9

-3x - 9 = -3x - 9

True.

Option 2

4(2x - 5) + 10 - 5x = 3x - 10

8x - 20 + 10 - 5x = 3x - 10

3x - 10 = 3x - 10

True

Option 3

5x + 4 = 3x + 4

False

Option 4

8x + 3 - 2 = 8x + 1

8x + 1 = 8x + 1

True.

Therefore, option 3 is False.
