Answer:
To do this, you need to multiply out the expressions. This is a bit tedious, but remember like FOIL for binomials, for these trinomials you must multiply each term. If you need a step-by-step, I'd be happy to provide it. Let me know.
Once you have simplified the expression, you get
-x-9/2x-4
But, the problem stipulates that a must equal 1. We can equivalently factor out the negative sign and put it on the denominator with no change to write
x+9/-(2x-4) = x+9/-2x+4
So, seeing where each coefficient corresponds between the two expressions, you get a = 1, b = 9, c = –2, and d = 4.
In total, he drank 2 liters.
In millimeters, this is:
2,000 milliliters.
1 liter = 1,000 milliliters
2 liters = 1,000×2
= 2,000 millimetres
The formula for volume of a cone = PI x r^2 x h/3
PI = 3.14
r = 8.5/2 = 4.25
h = 4.5
Volume = 3.14 x 4.25^2 x 4.5/3
Volume = 3.14 x 18.0625 x 1.5
Volume = 85.074375
Rounded to the nearest hundredth = 85.07 cubic cm.
