Black holes do not die; they evaporate.
They might seem like nothing, but they do evaporate eventually. Over a course of a billion years one might have half-evaporated.
That's not exactly what happens. What really happens is that they just absorb each other and become a bigger black hole.
It takes a dying star 20 times the size of our sun to create a black hole. So no they can't.
Any matter that enters the black hole will be destroyed. Also, it will increase the black hole's size.
The object swallowed by the black hole is destroyed; its mass is added to the mass of the black hole.
It evaporates.

Its called a Super Black-hole and scientists believe it is what holds all galaxies together.
They will merge to form a single black hole with the combined mass of the town that merged.
It gets bent toward the black hole's singularity.
Objects which approach a black hole will get sucked into it.
a star dying in space that sucks everything into it.
A black hole starts as a dying star. As the star gets smaller as it dies, the inner pressure becomes so powerful that the star implodes. When this happens, the smashed atoms of the dead star come together to form a neutron star. When this is crushed to nothing, a black hole is formed. If a black hole does not get enough energy, it will decrease in size and eventually explode.
