Answer:
7x-2, -x-6y+16, 5x-3
Step-by-step explanation:
I'm guessing the three expressions are:
1. 3(x+2) + 4(x-2)
2. 2(x+y) - 3(x+y) - (y+8) + 4(6-y)
3. 2(4x+3) - 3(x+1)
... 1. 3(x+2) + 4(x-2)
= 3x + 6 + 4x - 8
= 7x - 2
... 2. 2(x+y) - 3(x+y) - (y+8) + 4(6-y)
= 2x + 2y - 3x - 3y - y - 8 + 24 - 4y
= -x - 6y + 16
... 3. 2(4x+3) - 3(x+1)
= 8x + 6 - 3x - 3
= 5x - 3
Answer:
79200 feet is the volume of great wall.
Step-by-step explanation:
1 mile = 5280 feet
5280 feet × 15 feet = 79200
The height is the thing that we don't need to use, because you need volume, volume is the place where the wall at, the place is 79200 feet.
And I have question for you, have you ever go to China, did you go to the great wall, where did you come from.
