Answer:
2√13
Step-by-step explanation:
The distance formula is useful for this. One end of the vector is (0, 0), so the measure of its length is ...
d = √((x2 -x1)² +(y2 -y1)²) = √((6 -0)² +(-4-0)²)
= √(36 +16) = √52 = √(4·13)
d = 2√13 = |(6, -4)|

Answer:
x=4
or
x=-6
Step-by-step explanation:
did you know u can solve that equation on your calculator without much struggle?
Answer:
This looks like a quadratic root problem on first glance, lets simplify it.
Distribute the 3.
-5 + 3b + 27b - 15 + 9b^2
Simplify like terms of b.
-5 + 30b - 15 + 9b^2
Simplify constants
30b - 20 + 9b^2
Rearrange it so its easier to tell
9b^2 + 30b - 20
Now solve for the roots,
which gets you x = .5694 & x= -3.902
