5h + 2(11-h) = -5
5h +2*11 +2*(-h) = -5
5h +22 -2h = -5
3h + 22 = -5
3h = -5 -22
3h = -27
------
Therefore:
h=(-9), as 3 *(-9) = -27
Well the formula to convert Fahrenheit to Celsius is (temperature of Fahrenheit -32) * 5/9.
A = 13.95 ft^2
l = x
b = x + 1.4
a = l × b
13.95 = x × ( x + 1.4 )
13.95 = 3.1 × ( 3.1 + 1.4 )
13.95 = 13.95
length = 3.1
width = 4.5
