Can someone explain how to solve this?

-3*0 is 0-4 is -4 which is less than -2

-3*3 is -9-4 is -13 which is also less than 2

-3x-4<2

   +4   +4

add 4 to both sides

-3x<6

divide by -3 on both sides

x<-2

im not good at math this is prolly wrong

Option 1. Yes, the similarity ratio is 1:3.

Step-by-step explanation:

If the given triangles are similar then the ratio of all their sides are same.

So to prove the triangles as similar we will follow the statement reverse. Means to prove the triangles similar we will show the ratio of sides as same.  

Which clearly tells us that all sides are in the same ratio of 1:3 that means both the triangles are similar.
