it equals 54.
15x9=135
13"x9"x2"
13*9 = 117 square units
The answer will depend on what x9 is equal to..
2x2-y2
1 divided by 13 equals 13
13
First, you would add 13+13, which equals 26. Then you would subtract 26-13 which equals 13. So the problem would be 26-13=13.
234
63
Since there are 9 square feet in a square yard - the answer is 13 !
