Let A be a 6by4 matrix and B a 4by6 matrix show that the 6by6 matrix AB can not be invertible?

It is not possible to show that since it is not necessarily true.
There is absolutely nothing in the information that is given in the question which implies that AB is not invertible.

Is there a 6by6 rubik s cube?
Yes, It is called a professor's cube. i disagree with that .^ the 5x5 rubik's cube is the professor's cube. at least i think so. it's correct, the 5x5 is the professor but there is also a 6x6 and you can get it at v-cubes.com
How many 6by6 inch tiles needed to cover 925 sq inches?
Area of each tile = 6*6 = 36 sq inches. So number of tiles required = round-up(925/6) = 155. This, however, is the minimum number of tiles required and is based on the assumptions that the area is well behaved and that offcuts are mostly used. In real life, you should allow at least 5% for breakage and waste.
How do replace a vapor separator on a 1972 corvette?
first of all the vapor separator is attached to the top left side of the fuel tank you have to drain gas tank 2nd disconnect battery 3rd lift rear of car with jackstand's this will allow sufficient room for the gas tank to be removed when the time come's.4th crawl under rear of car ,you will see spare tire compartment it need's to be removed once that is accomplished you will have a view of the gas tank there will be two strapps visable you will need a floor jack with you one with a a good size platform say 6by6 or larger so when you remove the two strapps the gas tank has something to sit on.Their will be hoses connected to the upper part of the tank so be very careful.Only allow the tank with help from the floor jack to lower just enough to remove anything attached to tank,then lower tank.
