The domain of the function in this case will be for when the denominator is different from zero:
3x ^ 2- 3 = 0
3x ^ 2 = 3
x ^ 2 = 3/3
x ^ 2 = 1
x = + / - 1
Therefore the domain of this function are all reals without including x = 1 and x = -1
Answer:
I think it is 30 inches
Step-by-step explanation:
Since it decreases 2.75 then it will give you the answer of 20.75
4x+60+ x+15=180
5x+75=180
5x=105
x=21
Two linear angles are supplementary thereom
