1 x 45 = n      name the property you used?

well, since you're using 1, i'm pretty sure the property you're looking for the multiplication property of identity, which basically states that anything multiplied by one is itself.

1) 45 divided by 9 = 5\n2) 13 times 6 = 78

take the cube root of 729 u get 9

5 becuuse 45 = 5 * 9\nand 800 = 5 *160\n9 and 160 are coprimes

x=144 and y =1 or vice versa

it's 1 X 2 X 3 X 4 X 5 X 6 X 7 = 5040\n\nEDIT: Guess I was a bit slow here. Anyway, if you open your windows calculator. Click 'view' and pick 'scientific' you will see a much more complicated calculator.\n\nAmongst all the buttons is on that says N! (4th button for left on next to last row). That is the factorial button. Just hit '7' then the N! button for your answer.

B)48\n\nFirst of all, you can quickly eliminate choices A and C because the number of tiles (or area of the rectangle) has to be greater than or equal to the perimeter.  Then just use guess and check to see what dimensions give you a perimeter of 38 and an area of 48 or 52.  You'll come up with 3 x 16.

interesting!!!!  \n\n                 9x8 =72  7+2 =9\n                 9x9 =81  8+1 =9\n                 9x3 =27  2=7 =9

E -- divide 5 by 11 for your answer

do you mean 18 times the sq rt of 50, that would be 127.3\nthen subtract 21 times sq rt 40 divided by 3 times sq rt 2\nOr, is all of the subtraction part above the line\nSee if you can rewrite the problem

-5 x 2 x 2 x 2 x 2 x 2 (or, I guess you could say -1 x 5 x 2 x 2 x 2 x 2 x 2)
