Answer:
x=-1
Step-by-step explanation:
x+3≠0
x≠-3
x²+5x+6=x+3
x²+5x+6-x-3=0
x²+4x+3=0
x²+x+3x+3=0
x(x+1)+3(x+1)=0
(x+1)(x+3)=0
x+3≠ 0
so x+1=0
x=-1
I have to admit I don't know what exactly you are asking, but I think this is it: 10m/s.
Divide m/s by time.
Scalene and right, since:
There is a right angle
and scale means that there are no angles that are the same.
