So now you've shortened your "list of equations... read more

hello what is the product of (3x+2)(x+4) (answer)

So yes, the FOIL method works: "3x(x) + 3x(4) + 2x + 2(4) 3x2+ 12x + 2x + 8 3x2 + 14x + 8"   -Stephanie P.   Though many students cannot use methods such as FOIL because if confuses them even more.  SO, another way to go...

6/11x + 4 = 2/11x + 16 (answer)

I would first get rid of the fractions by multiplying everything by 11x (the denominator): 11x(6/11x + 4 = 2/11x + 16)        giving us 6 + 44x = 2 + 176x                        see how much easier...

three times two A (answer)

The way I think of this is realizing that its all multplication.  So just stick all the corresponding parts (similar to like terms when adding, but this is multiplying) together and find their products. 3 times 2 a = 3•2a or (3)(2a) or 3(2a).... this could go on.  For these problems,...
