Answer:
Width = 12 cm
Length = (2*12)+12 = 36 cm
Step-by-step explanation:
Width: x
Length: 2x + 12
2x + 2(2x+12) = 96 cm
2x + 4x + 24= 96
6x = 96 - 24
x = 72/6
x = 12
Answer:
Step-by-step explanation:
As we move from (0, 3) to (9, 0), we see x increasing by 9. This is the 'run.'
At the same time, we see y decreasing by 3. This is the 'rise.'
The slope of this line (graph) is m = rise / run = -3/9, or m = -1/3
Since we witness a decrease in y as we move from the first point to the second, we immediately suspect that the slope is negative.
