Answer: 9-3x
Step-by-step explanation:
You add like terms

9 - 3x
Length = width +6
L * (L - 6) = 135
L^2 - 6L = 135
L^2 - 6L -135 = 0
Length = 15
Width = 9
I says every time you INCREASE by 1 degree Farenheit you go up 59 degrees C, so it is false. Same for III, if you go up or down 1 degree C that's not a change of 59 in degrees F.
