Answer:
5.5x + 1.5
Step-by-step explanation:
P = 2(l + w)
P = 2(1.25x + 3 + 3x - 1.5)
The slope is the gradient
Gradient = rise/run
Gradient = -1/1
Gradient = -1
Slope = -1
If 0.4 liters is 1/2000 of the production batch, then the production batch is 2000 * 0.4 liters
2000 * 0.4 liters = 800 liters
