X +5 = -6x - 16
add 16 to both sides
x+21 = -6x
add 6x to both sides
7x+21=0
factor out the seven
7(x+3)=0
if 7 times (x+3) = 0 then (x+3) must equal zero because 7 times 0 is 0
so x+3=0
subtract three from both sides
x= -3

Step-by-step explanation:
Answer:
1. yes
2. no
Step-by-step explanation:
1. Yes.
since all our sides are the same, it doesn't matter which is the shorter or longer
a+a > 2a for all lengths a>0, since lengths of triangles can only be positive and greater than 0
equilateral triangles exist for a reason
2. no
a triangle will have exactly 180 degrees, no less, no more
30+70+110 >180
