$.75 bc 15 x 4 is 75 so that would make 75¢ or $.75
The slope-intercept of the line is
y= -2/3x + 2
Going up 2, left 3

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: 4x² + 12x + 9
Explanation:
Area = (2x + 3) (2x + 3) = 4x² + 6x + 6x + 9 = 4x² + 12x + 9
