Sound or vibration wave that is conducted
Answer: 81
Step-by-step explanation: 9 times 9 = 81
the like terms are: 10y, and -9y because they are both of the same variable, y.
The total space needed is 600 feet. Because 5 tables times 72 feet is 360 and 5 tables times 48 feet a part is 249. You add them and it comes out to be 600. It should be worked out like this 5(72+48)
Number 1 & 2 both goes in 200. Numbers 9,3, & 27 goes into 81. Numbers 10,5,4,8,20, & 25 goes into 200. Hope this helps
