You can’t really find the sum unless there is number to plug in for the variables.
Let width be x
Length would be x + 3
Area = L * W
Make an equation
(x) * (x+3) = 70
x^2 + 3x = 70
x^2 + 3x - 70 = 0
Quadratic formula
(-3 +/- rt 3^2 - 4 * 1 * (-70))/(2 * 1)
x1 = (-3 + 17)/2, x2 = (-3-17)/2
x = 7, x = -10
Dimension cannot be negative
Solution: width = 7
Length = 10
The dropping degree temperature will be -12°.
<h3>what is temperature drop?</h3>
- Temperature is a physical quantity that expresses the hotness of matter or radiation.
- Temperature drop (T1 −T 2) is a direct indication of energy extracted.
- For a given resource, it is dependent on T 2 which is in turn dependent on the minimum temperature of the process T1
- when the thermal conductivity is low and the coefficient of thermal expansion is large. In unsteady heat-exchange processes the maximum possible temperature drop usually determines the maximum rate at which heat exchange can occur.
A drop of 17 degrees means subtract 17 from given temperature
∴5°-17°=-12°
so, the Temperature drop will be -12°
