The letters each stand for the grade/finish for one side of the board. "AC" has one side grade "A" and one grade "C" meaning one side is sanded finish grade and the "c" side is meant to be unseen. where a "CD" would tell you both sides are a "unfinished" type grade, like roof decking material.
It depends on where you will use it. Both are good and readily available and both are suitable for interior use. Just consider appearance when making the decision.
Commonly available plywood grades are AC, BC, and CDX. These plywoods are usually made of pine, southern yellow pine or fir. AC plywood is for projects that require a smooth finish. A being the smooth side, C being somewhat rough. BC is ometimes used for floor underlayment. The B side is sanded and the C side being rough. CDX is an exterior grade plywood that is usually used for sheathing walls and roofs in homebuilding. Again C is rough, D rougher.
yes because ab plus bc is ac
I believe it means Before
AB + AC + BC = 48 AB + (AB +9) + (AB + 9 + 3) = 48 Solve and AB = 9 So AB = 9, AC = 18 and BC = 21
It is possible, depending on what on earth AC and BC are!
ac is After Christ and bc is Before Christ
The probability of ac and bc is 1/5.
A+BC+AC+B=A+BC+AC+B unless any of these variables has an assigned value.
it would be C because C is the last letter in ac and bc
BC
draw it out for ease. data: ab + 2 = ac bc-1 = ac therefore ab +2 = bc - 1 ab - bc = -3 perimeter is 62. /3 as most values are small difference. average distance is ~21. ab is smallest, guess it is 19. if so, ac would be 21. bc would be 22. does this add up? it actually does. i guess there is a mathematical way of doing this other than trial and error like the way i just did it, but i cannot see it right now
