x + y = -11

xy = 24

y = -11 - x

xy = x (-11-x) = -11x -x^2 =24

x^2 + 11x + 24 = 0

(x+8)(x+3) = 0

x = -8 or -3

y = -3 or -8

I multiplied get answer -3

I believe it is 1 and 19/24ths. I am not sure, but I will explain so you can check my math. First I found the common denominator, which is 24, then multiplied the top number by what I multiplied the bottom number by. For the 7/8 I multiplied by 3, which came out to be 21/24, and I multiplied the 11/12 by 2, which comes out to 22/24. If you add those up, you will get 43/24. Then, all you have to do is simplify.

Six 'n' four.

To find the number, we can divide 24 by 0.12. The result is 200, so the number that when multiplied by 0.12 gives the product 24 is 200.

You have to find two numbers that when multiplied together equal 24 and when added together equal 11. The numbers are 1 x 24 = 24 (1 + 24 = 25); 2 x 12 - 24 (2 + 12 = 14); 3 x 8 = 24 (3 + 8 = 11). The recangle is 3 tiles wide by 8 tiles long.
