If we assume that "r" is unknown: -9r+8 or 8-9r It cannot be simplified further.
The floor and ceiling each have areas of 72 square feet.In order to now the area of the walls, we would also need to knowthe height of the ceiling.
85 squared is an easy square to find. You take the 8 from 85 and times it by the number ahead of it. So 8x9=72. Then because there is a 5 after the 8 you add 25 at the end of 72 which gives you 7225. Be careful to only use this trick when there is a five at the end of the number.
8x9=72; 72-12=60; 60-8=52.
1+2+3+4+5+6+7+(8x9)=100
1+2+3+4+5+6+7+(8x9)
72
8x9=72
8x9=72
using only whole numbers there are six answers: 1x72 2x36 3x24 4x18 6x12 8x9
81 8x9 is 72
72
8 * 9 --- 72
1+2+3+4+5+6+7+(8x9)=100
1x72 2x36 3x24 4x18 6x12 8x9
