Answer:
5-a) The perimeter of the rectangle = 2(2x + 4x + 1,5) = 12x + 3
Step-by-step explanation:
From inspecting the graph, you can identify the y-intercept and the slope of the line shown.
The y-intercept is 200 gallons.
The slope is
75-200
m = ------------- = -12.5 gallons/minute
10 - 0
Thus, y = 200 gallons - [12.5 gallons/minute ]t
To answer the 2nd question, let t = 12 minutes and calculate y(12).
To determine how long it wld take to empty the tank, set the above formula equal to zero and solve the resulting equation for t.
well...
15 x 20 = 300
300+85 = 385
you can get 20 watches for $385
Given the expression below

To find n
Open the brackets

Collect like terms

Since, the sides are not equal,
Hence, there is no solution
