6x+1= (2x-1)(m+3)


multiple choice:

A) x= m+2 over 2m B) x= m+4 over 12+2m

C) x= 4-m over 2m D) x= m+4 over 2m


The multiple choice answers above are fractions. I will ONLY choose best answer for someone who shows all work and gets an answer above, thanks so much!

This is NOT conspiracy theory, but actual unedited live video
from the TV news. See for yourself... and explain what caused
all the short but very bright flashes of light appearing around
the WTC tower buildings as they collapsed... give sensible
explanations for these very bright flashes of light, and for God's
sake, don't say it was from the jet fuel fire!!!

Watch these unedited close-up videos
of short but very bright flashes going off
before and during the collapses, and
not the horizontal explosions shooting
out of the buildings at floors well below
the collapsing levels (which are
supposedly "pancaking" into each other
above)...

Concrete cannot become pulverised
into fine dust without the aid of high
energy explosives! Strength = 27-42
MPa, or typically 4000 psi tensile
strength, stronger than most plastics!

Explain all the concrete powder and why
there were NO solid pancaked concrete floors
sitting one on top of each other at ground
zero. Nothing!

1. Catalysts can help to bring the reactants together in the correct orientation
2. The chemical formula of a catalyst is written on the left hand side (reactant) side of an equation.
3. Catalysts can provide a surface on which the reaction occurs.
4. Catalysts increase the activation energy.
5. Catalysts increase the magnitude of the equilibrium constant, thus favoring product formation.
6. "Enzymes" are biochemical catalysts.
7. Catalysts increase the rate of a reaction.
8. Catalysts are slowly used up during the reaction and need to be replaced.
