Answer:
I don't know what is in the drop down question, but here are the answers for the others:
1. Triangle possible
2. Triangle possible
3. Triangle possible
4. Triangle not possible
Angles need to add up to 180.
The 2 smallest sides have to be greater summed up than the 3rd side.
Hope this helps!
Please put brainliest if possible.
(2/5)(x-1)<(3/5)(x+1) perform indicated multiplications
(2x-2)/5<(3x+3)/5 multiply both sides by 5
2x-2<3x+3 add 2 to both sides
2x<3x+5 subtract 3x from both sides
-x<5 divide both sides by -1 (remember to reverse direction of inequality sign when multiplying/dividing by a negative value)
x>-5

This equation can have a number of solutions. Typically when solving a two-variable equation, you are looking for the slope intercept form of the line. In this case that is:
y = 3x - 1
It is 3 because 3 is the lowest common factor
