The net diagram could be a cube because a cube has 6 identical sides.
Answer:
16.5 ft by 25.5 ft
Step-by-step explanation:
Let w represent the width of the garden in feet. Then w+9 is the garden's length, and w(w+9) represents its area.
The surrounding walkway adds 8 feet to each dimension, so the total area of the garden with the walkway is ...
(w+8)(w+9+8) = w^2 +25w +136
If we subtract the area of the garden itself, then the remaining area is that of the walkway:
(w^2 +25w +136) - (w(w+9)) = 400
16w + 136 = 400 . . .simplify
16w = 264 . . . . . . . . subtract 136
264/16 = w = 16.5 . . . . . width of the garden in feet
w+9 = 25.5 . . . . . . . . . . .length of the garden in feet
Answer:
1`. y = 4x+6
2. y = -6x + 29
3. y= 3x+1
4. y = x -2
5. y = 11.5x+ 3
6. y = -2x -4
Step-by-step explanation:
Answer:
The correct answer is c = -8/3.
Step-by-step explanation:
The first step in solving this problem would be to simplify by combining like terms on the left side of the equation.
6c - 8 - 2c = -16 + c
4c - 8 = -16 + c
Then, we can subtract c from both sides of the equation to get rid of the positive c on the right side of the equation.
4c - c - 8 = -16 + c - c
3c - 8 = -16
Next, we can add 8 to both sides of the equation.
3c - 8 + 8 = -16 + 8
3c = - 8
Then, we can divide both sides of the equation by 3.
c = -8/3
Hope this helps!
